A watch was purchased for $25. The wholesale cost was $16. What percentage was the markup? 64% 1.56% 56.25% 0.56%

OpenStudy (mrnood):

what was the mark up in $?

OpenStudy (mackenzie2013):

I dont know, I'm confused.

OpenStudy (mrnood):

the watch cost $16 and was sold for $25 how much was the profit ('mark up')?

OpenStudy (mackenzie2013):

10?

OpenStudy (mrnood):

When you post a question on a topic - such as percentages we have to make some assumptions that you have some 'supporting knowledge' - such as subtraction "10?" looks like a guess to me If I gave you $25 for a watch and you had to give $16 of that to the person YOU bought it from - how much would oyu have left?

OpenStudy (mackenzie2013):

10.

OpenStudy (mrnood):

That is not correct

OpenStudy (mackenzie2013):

Why dont you try explaining the steps to me so I can try to understand it.

OpenStudy (mrnood):

I AM trying to lead you through the steps the first step is to work out the amount of profit in dollars this involves a simple subtraction When you post a question on a topic - such as percentages we have to make some assumptions that you have some 'supporting knowledge' - such as subtraction. If you cannot do the simpe subtraction then there is little chance that I will be able to guide you through working out a percentage SO to work out the profit (mark up) youneed to subtract the cost of buying from the price of selling. buying costwas $16 selling price was $25 what was the mark up in $ ?

OpenStudy (shelby33):

it would be 1.56% because u will divide

OpenStudy (mrnood):

@shelby33 a) that is wrong b) it is against the rules to post answers

OpenStudy (mackenzie2013):

MrNood, I am not trying to be a smarty, but simply trying to understand this. I would appreciate it if you would be a bit more understanding for I am trying to learn. If you can't do that, I will find someone else. 25- 16 is 9.

OpenStudy (mrnood):

OK $9 is correct you wrote $10 (twice)

OpenStudy (mrnood):

SO now we have to find out what PERCENTAGE that is

OpenStudy (mackenzie2013):

I was having a blonde moment, sorry.

OpenStudy (mrnood):

the way to work that ou is % markup = 100 * $markup/$buying price

OpenStudy (mackenzie2013):

So i take the percent and divide it by the markup?

OpenStudy (mrnood):

no - that is not what the equation says percentage markup = 100 times markup in dollars divided by buying price in dollars so put the numbers into that equation and use your calculator to work out the % markup in dollars = $9 buying price in dollars = $16 so put those numbers into the equation and use your calculator to work out the correct answer

OpenStudy (mrnood):

Your answer = 100*9/16 % Can you work that out?

OpenStudy (mackenzie2013):

64%

OpenStudy (mrnood):

no - that is not correct

OpenStudy (mrnood):

There are only 4 options - I am not going to confirm or deny any other guesses Please use the equation above, and your calculator - then you will have worked out the correct answer
