Question

Mr. Torres bought 3 chairs on Saturday. He paid d dollars for each chair. Mr. Torres received $15 dollars in change when he bought the chairs. Which expression can be used to find the total amount Mr. Torres paid for these chairs

Answer 1

Answer: c. 3d + 15

Step-by-step explanation:

Mr. Torres paid d dollars for each of the three chairs which gives the expression of:

= 3 * d = 3d

He then paid with an amount that was greater than this 3d and got a change of $15.

That total amount that he paid is therefore, the price of the three chairs added to the $15 that he received back.

= 3d + 15
