2 x 37 = 7.37-7.4 = 29..15 x 29.6 = 4.......
Xavier bought a shirt that was on sale for 20% off the original price. He also used a coupon that gave him an additional 15% off the sale price of the shirt. The original price of the shirt was $37. What is the new price of the shirt before tax?

-
0.2 x 37 = 7.4
37-7.4 = 29.6
.15 x 29.6 = 4.44
29.6 - 4.44 = 25.16

ur answer is 25.16

Any number multiplied by 1 is equal to itself. Any number multiplied by a percentage of 1 is equal to that percentage of itself.

0.20 = 20% of 1
0.15 = 15% of 1

So, multiply the 37 dollars by 0.20, and you'll get 20% of it.

37 * 0.20 = 7.40

So subtracting the 7.40 from the 37.00, you get $29.60 as the sale price. To get the additional 15%, multiply 29.60 by 0.15.

29.60 * 0.15 = 4.44

So subtract the additional 4.44 from 29.60, and you get $25.16 as the final price before tax.


ANSWER

$25.16

-
so, the total discount on shirt will be ( 20% +15%) = 35 %

original price of shirt is $37

$37 is 100%
y is 35%

y = (37x35)/100

y = $12.95 is the off price

now, $ 37 - $ 12, 95 = $ 24.05 ---- this is the price after sale

-
Original price = $37

20% off original price = 37 - (37 * 0.2) = $29.6

Further 15% reduction:

29.6 - (29.6 * 0.15) = $25.16

-
$25.16
