The school story is running low on erasers for pencils they wanted to order more so they looked at the price for four brands which one is the best buy brand a 24 $2.50 brand B 35 for $3.25 Brand c 545.25 Brandy 100 for $10

To determine the best buy brand, we need to compare the price per eraser for each brand.

For Brand A, there are 24 erasers for $2.50, so the price per eraser would be:

$2.50 / 24 = $0.1042 per eraser

For Brand B, there are 35 erasers for $3.25, so the price per eraser would be:

$3.25 / 35 = $0.0929 per eraser

For Brand C, the price is given as $545.25, but it is unclear how many erasers are included. Without this information, we cannot calculate the price per eraser accurately.

For Brand D, there are 100 erasers for $10, so the price per eraser would be:

$10 / 100 = $0.10 per eraser

Comparing the price per eraser, we can see that Brand B has the lowest price per eraser at $0.0929. Therefore, Brand B would be the best buy.
