Ivanna received a $80 gift card for a coffee store. She used it in buying some coffee that cost $8.03 per pound. After buying the coffee, she had $47.88 left on her card. How many pounds of coffee did she buy?

First, we can calculate how much money Ivanna spent by subtracting her remaining balance after buying the coffee from the original amount on the gift card.

amount spent = $80 - $47.88 = $32.12

Now, we can calculate how many pounds of coffee she bought by dividing the amount she spent by the price rate of coffee by pound.

[tex]\$32.12 \div \dfrac{\$8.03}{1 \text{ lb}}[/tex]

[tex]= \$32.12 \times \dfrac{1 \text{ lb}}{\$8.03}[/tex]

[tex]= \dfrac{32.12}{8.03} \text{ lb}[/tex]

[tex]= \boxed{4 \text{ lb}}[/tex]

So, Ivanna bought 4 pounds of coffee.

Answer: Ivanna bought 4 pounds of coffee for an amount of$32.12.

Step-by-step explanation:

According to the question,

Money with Ivanna initially: $80

Money with Ivanna later: $47.88

step 1: here we need to find the difference between the amount initially and later,

Difference between the amount initially and later: $80 - $47.88 = $32.12

Given,

Price of coffee per pound: $8.03

Step 2: now we divide the amount spent by the price per unit of coffee,

that is: $32.12/$8.03 = 4

so the answer is Ivanna bought 4 pounds of coffee for an amount of$32.12
