Question

Dan's business loses $9 each day. Which equation would be used to show how much money Dan's business has lost in a week?

A. -9 × 7
B.-9 × (-7)
C.9 × 7
D.9 × (-7)

Answer 1

Answer: -9 x 7

Explanation:

It's really simple, since in this case, you're multiplying a negative times a positive, your outcome will be negative, which is what we want because Dan is losing money. If it were B. -9 x (-7) that would make the answer 63 not -63 which means Dan's business would be earning money, not loosing it.

Answer 2

A. Because it shows negative making it less confusing showing that he loses 63$ per week.
