A magazine subscription costs $45 per year at the beginning of each year, or $115 now for a three-year subscription. If the subscriber elects to pay the $115 now, the rate of return on the investment will be nearest to:

B. 18%

Explanation:

Assuming  another different subscriber decides to go for the $45 per year subscription cost then I'm three years would have paid ($45*3=$135).

The rate of return on the investment for the subscriber that elects to pay the $115 now will be;

$135-$115=$20,

we find the percentage of the difference from $115.

=20/115 x 100 = 17.4% nearest to 18%.

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
