Question

Paul purchased 3 video games for $17.25 each. Which expression is the best choice to help him determine the total amount of money he spent?
A. (3) × (−17.25) = −51.75; He spent $51.75.
B. (−3) × (17.25) = −51.75; He spent $51.75.
C. (3) × (17.25) = 51.75; He spent $51.75.
D. (−3) × (−17.25) = 51.75; He spent $51.75.

Answer 1

Hello! B and D are eliminated from the start, because you don't multiply by a negative to get the amount you spent. In reality, you would multiply the number of games by the cost of it to get the real price. A doesn't make too much sense, but the negative could represent how much he spent from his allowance. Even with that, it's really not the best answer. The only answer that really works is C. The answer is C.

Answer 2

Paul purchased 3 video games for $17.25 each, that means each game is $17.25. All you have to do is multiply 17.25 by 3. Your answer would be C. (3) x (17.25) = 51.75; He spent $51.75.
