Question

Last summer, Mike received a tip from 35% of his babysitting customers. If he had 20 customers, how many customers gave Mike a tip?

Answer 1

To solve you'll set up a proportion.

35/100 = x/20

cross multiply.

100x = 700

Now divide by 100.

x = 7

Answer 2

7 I think because you multiply 20 times 0.35
