Lydia bought a shirt at 20% off its retail price of $40. She paid 5% tax on the price after the discount. How much did Lydia pay for the shirt?
@dude
Cool Do you know how to get 20% off of $40?
Uhm the only way I know is to look it up... so in other words no
Okay, so first you want to convert the 20% to a decimal, do you know how to do that?
0.20
0.20
That looks good, now to know what 20% of the $40 is, multiply the decimal and the price
0.2*40=8?
Yes Since that is a discount, subtract 8 from the original price Cost - discount = new cost 40-8
40-8=32 i did it in my head so it might be wrong
That is right :P
Okay now we need more 1 part it says there is a 5% tax after the discount
You want to repeat a similar pattern by finding what 5% of 32 is
That is the hard part okay so... how???? omg i am dumb
What is 5% as a decimal?
0.05 okay so do i basically do what i did
Multiply them now \(0.05\times32\)
0.5x32=16
Watch out with decimals It is 0.05 times 32, not 0.5 times 32
shoot
0.8
Might want to re-check that \(0.05\times 32\) should be 1.6
okay hold on i am so stupid i cant even calculate this OML Thanks
next
It's fine, everyone makes typing mistakes just try to make sure you type it correctly once you put it in Since this is tax, it is added to the cost So do 32+1.6 =
32+1.6=33.6 right
Looks good, that is your answer
so the price is $33.60?
Yeah
Will I have to open a new question for you to help me solve the next one
Sure
But i cant figure out how to open another math one OML I AM STOOPID
Close this question and then you should be able to post another one
how shall i close it
i figured it out
