Question 7 • Pre-Algebra - MA3119 A ? Distance Learning

Last year, Gena’s food cart business was $225 in debt. This year, the debt has tripled. Which expressions show how much Gena’s business is currently in debt? Check all that apply.

Answer
A
225(3)
B
(3)(–225)
C
–225 + 3
D
3 – 225
E
–225(3)

Explanation

A debt of $225 is represented by –225. If the debt triples, multiply –225 by 3: (3)(–225) or –225(3), which both equal –$675. Choices B and E show the current debt; A is positive, and C and D add or subtract 3 rather than tripling the debt.
