Final answer:
After calculating both totals, your friend spent a total of $69 while you spent $62.50, making your friend the one who spent more by $6.50. The options provided in the question do not match this result.
Step-by-step explanation:
To solve this problem we need to calculate the total cost for both you and your friend based on the quantities and prices of the items purchased from the school spirit store.
Your friend's total cost is calculated as follows:
- Two T-shirts: 2 × $15 = $30
- One sweatshirt: 1 × $25 = $25
- Four large stickers: 4 × $3.50 = $14
Adding these amounts together gives your friend's total:
$30 + $25 + $14 = $69
Your total cost is calculated as follows:
- Three T-shirts: 3 × $15 = $45
- Five large stickers: 5 × $3.50 = $17.50
Adding these amounts together gives your total:
$45 + $17.50 = $62.50
Now, to compare who spent more:
$69 (friend's total) - $62.50 (your total) = $6.50
Therefore, your friend spends more by $6.50, not $7.50 or $12.50 as the given choices suggest. The options provided in the question seem incorrect based on the calculation. If the choice 'Your friend spends more by $6.50' were available, that would be the correct answer.
