Question

Sam paid $4.50 to have two shirts cleaned. If the dry cleaning service charges the same amount for any shirt, which equation can be used to represent the total cost, c, of having n shirts cleaned? A c = 4.5n B. c = 2.25n C. c = 4.5 +n D. c = 2.25 + n

Answer 1

Sam paid $4.50 to have two shirts cleaned.

If the dry cleaning service charges the same amount for any shirt then it means that for each shirt the rate is

`(\$4.50)/(2)=\$2.25`

If there are n shirts then the total cost (c) of the shirts can be represented by the following equation.

`c=2.25n`

If you substitute n = 2 shirts into the above equation then the total cost will be $4.50 which satisfies the given information.

Therefore, the correct answer is option B
