The school store is running low on erasers for pencils. They want to order more, so they look at the prices for 4 brands. Which one is the best buy? Brand A: 20 for $2.50 Brand B: 35 for $3.25 Brand C: 50 for $5.25 Brand D: 100 for $10.00 (1 point) Responses Brand A Brand A Brand B Brand B Brand C Brand C Brand D
I already calculated everything. Everything is money btw
The best buy would be Brand B, with 35 erasers for $3.25.
You have to divide the money by the whole numbers
I apologize for the confusion. Let's calculate the cost per eraser for each brand:
Brand A: 2.50 ÷ 20 = $0.125 per eraser
Brand B: 3.25 ÷ 35 = $0.093 per eraser
Brand C: 5.25 ÷ 50 = $0.105 per eraser
Brand D: 10.00 ÷ 100 = $0.10 per eraser
Therefore, the best buy would be Brand B, with a cost of $0.093 per eraser.
Round to the hundredths
Apologies for the oversight. Let's round the cost per eraser to the hundredths decimal place:
Brand A: $0.125 per eraser
Brand B: $0.093 per eraser
Brand C: $0.105 per eraser
Brand D: $0.10 per eraser
After rounding to the hundredths decimal place, the best buy is still Brand B with a cost of $0.09 per eraser.
