Marsha buys x pens at $0.70 per pen and one pencil for $0.10. Which function gives the total amount Marsha spends? A C(x) = (0.70+ 0.10)x B C(x) = 0.70x + 0.10 C(x) = 0.70x + 10 C(x) = 0.70x + 0.10x

B C(x) = 0.70x + 0.10

Step-by-step explanation:

Number of pens = x

Cost of pens = $0.70

Number of pencil = 1

Cost of pencil = $0.10

Total cost, C(x) = (Number of pens * Cost of pens) + (Number of pencil * Cost of pencil)

= (x *0.70) + (1 * 0.10)

= 0.70x + 0.10

C(x) = 0.70x + 0.10

The answer is

B C(x) = 0.70x + 0.10

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

- 70

this is the answer for you hope it
