Question

The retail price of a suit is d dollars. Connor bought the suit with a 15% discount. Which expressions correctly represent the price that Connor paid for the suit? Check all that are true.

0.85d
d - 0.15d
d - 15d
d + 0.15d
1.15d

Answer 1

Expressions correctly represent the price that Connor paid for the suit are 0.85d and d - 0.15d .

Explanation:

As given

The tax on the order is $1.571 and the final total for an order is $27.751 .

15% is written in the decimal form

`= (15)/(100)`

= 0.15

Thus

Discount price = 0.15 × Retail price of a suit

= 0.15 × d

= 0.15d

Thus

Price that Connor paid for the suit = Retail price of a suit - Discount price .

Put all the values in the above

= d - 0.15d

= 0.85d

Therefore the expressions correctly represent the price that Connor paid for the suit are 0.85d and d - 0.15d .

Answer 2

Both of the first two choices represent the amount Connor paid.

15% = 0.15, so when you subtract 15% of d from d, you get the 2nd expression. When you simplify that, you get the 1st expression.

The correct choices are ...
• 0.85d
• d - 0.15d
