Question

A painter charges $20 for every hour that he paints. Let h represent the number of hours he paints and e represent his earnings. Select all the statements that are true.

Answer 1

the 3 correct ones are b,c,e

Answer 2

See below.

Explanation:

He earns $20 per hour, so when you multiply 20 by h number of hours, you get the amount he earns for working h hours.

The equation is

e = 20h

A is false.

B

e = 20h

20h = 500

h = 25

B is true.

C is false. He earns $20 per hour, not 20h dollars per hour.

D

e = 20h

For 10 hours, h = 10.

e = 20 * 10 = 200

He earns $200 for 10 hours.

D is false.

E

If he raises his hourly rate by $2, he will earn $22 per hour. The new equation is

e = 22h

E is true.
