Answer:
Step-by-step exTo answer the math problem, you need to follow these steps:
a. To evaluate c(2.5), you need to substitute p with 2.5 in the equation c = 3.49p. This means that you need to multiply 3.49 by 2.5 and get the result. You can use a calculator or do the calculation by hand. The result is c(2.5) = 8.725.
b. To describe what your result means in the context of this problem, you need to relate the value of c(2.5) to the cost of blueberries and the amount purchased. The result means that if Hannah buys 2.5 pounds of blueberries at $3.49 per pound, she will pay $8.725 in total.
