Which equation could represent "the total cost of bananas at the store that sell for $0.89 per pound" where b is the number of pounds of bananas and C is the total cost?
A. C(b) = 0.89b
B. C(b) = 0.89 + b
C. C(0.89) = b
D. C(b) = 0.89 - b

Respuesta :

Equation that represents total cost is C(b) = 0.89b

Step-by-step explanation:

  • Step 1: Given total cost of bananas is C, number of pounds is b and cost of bananas per pound is $0.89, form equation based on this.

⇒ Total Cost = Number of pounds of bananas × Cost per pound

C(b) = 0.89b
