Students donated 2,500 cans of food to the local food pantry last year. they donated 4,000 cans this year. what is the percent increase in the number of cans donated?

Take the original figure of cans and divide it by the increase of cans, then multiple by 100 to convert to a percentage.

4,000 - 2,500 = 1,500 cans is the difference and the increase

1,500 ÷ 2,500 = .6

.6 × 100 = 60% increase in the number of cans donated

To test our answer, multiply 2,500 cans from last year by the percentage increase represented as a decimal number: 2,500 x 1.6 = 4,000 cans

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
