Final answer:
Jennifer needs an additional $7.59 after paying $20 to cover the cost of 2.55 pounds of turkey and 3.7 pounds of cheese. The total cost of her purchase was $27.593.
Step-by-step explanation:
Jennifer buys 2.55 pounds of turkey at $5.96 per pound and 3.7 pounds of cheese at $3.35 per pound. To find out how much more money she needs after paying $20, we need to calculate the total cost of the turkey and cheese and then subtract the amount she has already paid.
First, we calculate the cost of the turkey:
- 2.55 pounds × $5.96 per pound = $15.198
Then, we calculate the cost of the cheese:
- 3.7 pounds × $3.35 per pound = $12.395
Next, we add the cost of the turkey and cheese to find the total cost:
- Total cost = $15.198 (turkey) + $12.395 (cheese) = $27.593
Now, we subtract the amount Jennifer has already paid to find out how much more she needs:
- Amount more needed = Total cost - Amount paid
- Amount more needed = $27.593 - $20 = $7.593
Jennifer needs an additional $7.59 (rounded to the nearest cent) to cover her purchase.
