What is the original price, in dollars, of the shirt?

Question

Jackson buys a new shirt. The shirt is 25% off of the original price. Jackson pays a total of $11.34 for the shirt, which includes sales tax of 8%. What is the original price, in dollars, of the shirt?

Answer 1

first find the price of the shirt before the sales tax

108% of p=$11.34

1.08*p=11.34

p=11.34/1.08

p=$10.50 before adding the sales tax

now find the original price of the shirt

if the shirt is on sale for 25% off, then you pay only 75% of the original price

75% of what number is $10.50

75%*p=10.5

0.75*p=10.5

p=10.5/0.75

p=$14.00 is the original price of the shirt
