Question

1. on average, 8 potatoes cost $1.50 at a farmer’s market. fernando needs 22 potatoes.

a. estimate the cost of 22 potatoes. (remember that estimation is not the same as actually solving) explain your estimation.
b. how much will it cost fernando to buy 22 potatoes? how does this compare to your estimate?
c. how many potatoes could fernando buy with $7?

Explanation:

Step1: Find the cost of one potato

The cost of 8 potatoes is $1.50. So the cost of one potato is $1.50\div8 = 0.1875$.

Step2: Calculate the number of potatoes for $7

Let the number of potatoes be $n$. We know that the cost per - potato is $0.1875$. So $n=\frac{7}{0.1875}=\frac{7}{\frac{3}{16}}=7\times\frac{16}{3}=\frac{112}{3}\approx37.33$. Since we can't buy a fraction of a potato, Fernando can buy 37 potatoes.

Answer:

37
