rita received a $80 gift card for a coffee store. she used it in buying some coffee that cost $7.37 per pound. after buying the coffee, she had $57.89 left on her card. How many pounds of coffee did she buy?​

Explanation:

Let's first find out how much money Rita spent on coffee:

$80 (initial balance) - $57.89 (remaining balance) = $22.11 spent on coffee

Now, let x be the number of pounds of coffee that Rita bought. Since the coffee costs $7.37 per pound, we can set up the equation:

$7.37x = $22.11

Solving for x, we can divide both sides by $7.37:

x = 3

Therefore, Rita bought 3 pounds of coffee.

Answer 2

3 pounds of coffee.

Explanation:

Equation

y = -7.37x + 80

substitute 57.89 for y

57.89 = -7.37 + 80 Subtract 80 from both sides

57.89 - 80 = -7.37 + 80 - 80

-22.11 = -7.37x Divide both sides by -7.37

3 = x

3 pound of coffee
