Question

Jessica received a $80 gift card for a coffee store. She used it in buying some coffee that cost $7.76 per pound. After buying the coffee, she had $33.44 left on her card. How many pounds of coffee did she buy?

Answer 1

Answer:

Set up an equation

80 dollars is what we started off with

$7.76 per unknown pounds is the money you used

Jessica is left with 33.44 now

80 - 7.76x = 33.44

-80               -80

-7.76x = -46.56

/-7.76    /-7.76

x = 6 pounds

Answer 2

ANSWER: she bought 6 pounds of coffee

EXPLANATION:

first let’s see how much she spent on coffee. To do this subtract the amount she has left for what she started out with.

80 - 33.44 = 46.56

That’s how much she spent on coffee.

We know coffee is 7.76 per pound so we just need to divide the amount she spent by the coast per pound.

46.56 divided by 7.76 = 6

So she bought six pounds.
