Question

Suppose tuna is on sale for $0.90 a can, and you have a coupon for $0.40 off your total purchase. write a function rule for the cost of n cans of tuna.

A. C(n) = 0.09n- 0.40
B. C(n) = 0.40n - 0.90
C. C(n) = (0.90 + n) - 0.40
D. C(n) = (0.40 + n) - 0.90

Answer 1

A

Explanation:

C(n) = 0.90n-0.40

Just took the test.

Answer 2

Answer: Hence, Option 'A' is correct.

Explanation:

since we have given that

Cost of per cans = $0.90

Let number of cans of Tuna be n

so, Total cost of n cans be

`0.90* n\\\\=0.90n`

Amount of coupon Tuna get off on total purchase = $0.40

So, According to question,

`C(n)=0.09n-0.40`

Hence, Option 'A' is correct.
