A Customer went to a garden shop and bought some potting soil for $12.50 and 6 shrubs. If the total bill was $71.00, how much did each shrub cost if they all cost the same. Choose a label a variable for this situation. Write a equation using the variable that would answer the question. Solve your equation and check your answer. Use the solution to write a sentence answer to the word problem/.
Total bill - potting soil = X x = prices of 6 shrubs x / 6 = price of each shrub dont forget to click good answer
what do i divide?
ok so have you worked out what x is yet? to work out x you do Total bill - potting soil price
So divide 71 divided by 6?
Im mixed up
no wait your rushing ahead
what i said was the first step to do is TOTAL BILL - THE PRICE OF POTTING SOIL
so what was the total bill?
and what was the price of potting soil?
the bill was $71.00 and the soil was $12.50
great so all you do is total bill - price of potting soil which is the same as 71.00 - 12.50 = ??
58.50
It is 58.50??
yes
now that means we have worked out how much 6 shrubs cost
it costs 58.50?
yes but to work out the price of 1 shrub what do you think we do if that was the price of 6 shrubs
6 shrubs = 58.50 1 shrub = 58.50 / 6
$9.75
great
So
ok now to write an equation we just replace the answer that we dont know by x so for example the first step we done which was Total bill - price of potting soil = ??? because we dont know the answer we can call it x
do you get that so far?
71 + 12.50 is 83.50
but obviously we do know the answer because we already worked it out but lets just pretend we are seeing this question for the first time
its actually 71 - 12.50
So the answer would be 71.00 - 12.50 = 58.50
we're not after the answer at this stage but yes replace 58.5 with x
so 71 - 12.5 = x
X = 58.50
we are trying to work out the equation now not the answer
thats right x = 58.50
now the equation we can write is ps = per shrub price x = 71 - 12.5 x / 6 = PS so now that is the equation we will use x / 6 = ps
and to solve using that equation we need to know what x is first remember x = total bill - price of potting soil which is the same as x = 71 - 12.5 you already worked out x and you got x = 58.5
so now in the equation where it says x just replace it by the number 58.5 x / 6 = PS which will look like 58.5 / 6 = PS now to get the answer for PS you just calculate what is written which is 58.5 divided by 6 will give you PS
You there?
yes
You there now?
