On Andrew's note, he wrote that -5 > -10. Which number did he indicate was the greater number? 0° -10° -5°

$0.45

Step-by-step explanation:

Discount is 15% so that means you only need to pay (100 - 15)% = 85% of the total cost of the eraser.

Cost with discount = $0.50 × 85% = $0.50 × 0.85 = $0.43.

Sales tax is 6.25% so you will pay 6.25% × $0.43 = $0.03 for sales tax.

Total cost with sales tax = $0.43 + $0.03 = $0.45.
