Question

One pound of grapes costs $1.55. Which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes?

Answer 1

Answer:

Given the statement: One pound of grapes costs $1.55.

Let x be be the cost of 3.5 pounds of grapes.

Equivalent ratios states that the  two ratios that express the same relationship between numbers.

Therefore, by equivalent ratio:

$\frac{1 pound}{cost of 1 grapes} =\frac{3.5 pound}{cost of 3.5 grapes}$

then, we have;

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

Cross multiply the above equation; we hve

$x = 1.55 \times 3.5$

x = 5.425

therefore, the cost of 3.5 pounds of grapes is, $5.425
