In 4 weeks a school race $2560 for a health and fitness awareness students collected donations in 5 days each week the principal agreed to make one donation that was the same as the amount collected in a-day if an equal amount was collected each day how much did the principal donate.

Total amount contributed by principal = 4×128 = $512

Step-by-step explanation:

In 4 weeks, the school raised $2560 for a health and fitness awareness students collected donations in 5 days each week. Total number of days for which collection was made

= 5×4 = 20 days

The principal agreed to make one donation that was the same as the amount collected in a day each week. Let amount per day be x since all days are of equal amount, this means

A week = 5x

4weeks = 20x

20x = 2560

x = $128

The principal contributed $128 in each week

Total amount contributed by principal = 4×128 = $512
