Sara has a gift card for Six Town's Bakery and bought the following items.
6 muffins for $0.45 each
2 boxes of cookies for $2.70 each
1 coffee cake for $3.72
Sara estimates she has $8.00 left on her gift card. What assumption did Sara use to make her estimate
Sara assumed that she spent the full value of the items she bought, without considering any possible discounts or taxes. She also assumed that there are no additional costs or fees associated with her purchases.
To estimate that she has $8.00 left on her gift card, Sara likely assumed that she spent the exact calculated total for the items she purchased (subtotal) and that there were no additional charges or discounts applied. She did not consider any taxes, fees, or other costs that may have been included in the final amount.
To determine the assumption Sara made to estimate the remaining balance on her gift card, we need to understand how she came up with the estimate of $8.00.
First, let's calculate the total cost of the items Sara bought:
6 muffins at $0.45 each: 6 * $0.45 = $2.70
2 boxes of cookies at $2.70 each: 2 * $2.70 = $5.40
1 coffee cake: $3.72
Now let's add up the individual costs:
$2.70 (muffins) + $5.40 (cookies) + $3.72 (coffee cake) = $11.82
Sara estimates she has $8.00 left on her gift card. Based on these numbers, she has assumed that she spent $11.82 in total and that the remaining balance on her gift card is the original amount ($11.82) minus the estimated amount spent ($8.00).
Assumption Made: Sara assumed that she spent $11.82 in total, and then subtracted that amount from the original value of her gift card to arrive at an estimate of $8.00.
