Answer

Explanation:

Step1: Set up ratio - cost per pound

The cost of 1 pound of grapes is $1.55, so the ratio of cost to pounds is $\frac{1.55}{1}$.

Step2: Let $x$ be the cost of 3.5 pounds

The ratio for 3.5 pounds of grapes is $\frac{x}{3.5}$.

Step3: Equate the ratios

Since the cost - per - pound ratio is the same, we have $\frac{1.55}{1}=\frac{x}{3.5}$.

Answer:

$\frac{1.55}{1}=\frac{x}{3.5}$
