Total money needed= $5,000
Percentage raised= 75%
<u>To calculate the amount collected and the difference required, we need to use the following formulas:</u>
Total collected= 5,000*0.75
Total collected= $3,750
Difference= 5,000 - 3,750
Difference= $1,250
10 x 10 = 100
100 x 5 = 500
10 x 10 x 10 = 1,000
1,000 x 4 = 4,000
4,000 + 500 = 4,500
