Answer

Now solve:

Let s represent the number of students who participate in the fundraising program.

=

The cross products are equal.

100 •s = 70 • 480

100s= 33,600

s is multiplied by 100.

Divide both sides of the equation by 100 to undo multiplication.

=

s = 336

Since 336 is close to your estimate of 375, 336 is a reasonable answer.

336 students participate in the fundraising program.

Answer

25% of the exercises are completed, so 20 minutes is 25% of the total time needed.

=

Set up a proportion. The “of” part is what you have been asked to find.

=

The cross products are equal.

100 • 20= 25 •m
