Question

The amount Cami raised during last year’s charity walk, $45.50, is 7/10 of the amount she raised this year. Which equation represents n, the number of dollars she raised this year?

A. 45.50(7/10) = n
B. 45.50 = 0.7n
C. 45.50 + n = 7/10
D. 45.50 = 0.7 + n

Answer 1

n=45.50(10/7) or you could arrange it in,
0.7n=45.50

So, the answer is B

Answer 2

Option B. (0.7)n = 45.50

Explanation:

If n represents the number of dollars she raised this year then as per question the equation will be (7/10)n = 45.50

(0.7)n = 45.50

Therefore option B. 45.50 = 0.7n is the answer.
