Ms. Pine needs to buy more erasers for our classroom because they are always mysteriously disappearing. Based on the chart from the office supply catalog, how much will it cost her to buy 100 erasers personalized with her name on it?

Question

Number of Erasers Cost
1 - 20 $6.35
21 - 40 $5.70
$3.05
41 - 60
-61 - 80
81 - 100

Answer 1

The cost for 100 erasers personalized with Ms. Pine's name on it can be calculated as follows:
- The cost for the first 20 erasers is $6.35 per eraser.
- The cost for the next 20 erasers (21-40) is $5.70 per eraser.
- The cost for the next 20 erasers (41-60) is $3.05 per eraser.

To calculate the total cost, we need to add up the costs for each range separately:
- For the first 20 erasers: $6.35 x 20 = $<<6.35*20=127>>127
- For the next 20 erasers: $5.70 x 20 = $<<5.70*20=114>>114
- For the next 20 erasers: $3.05 x 20 = $<<3.05*20=61>>61

Total cost = $127 + $114 + $61 = $<<127+114+61=302>>302

Therefore, it will cost Ms. Pine $302 to buy 100 erasers personalized with her name on it.
