You earn $8 an hour doing cleanups and $12 an hour painting. last spring and summer, you worked a total of 400 hours and earned $3,800. how many hours did you spend doing cleanups? how many hours did you spend painting?

Step-by-step explanation:

Let p represent the number of hours spent painting. Then the hours spent doing cleanups can be represented by 400-p, and total earnings are ...

  12p +8(400 -p) = 3800

  4p +3200 = 3800 . . . . . . simplify

  4p = 600 . . . . . . . . . . subtract 3200; next, divide by 4

  p = 150 . . . . . . . . . . . hours spent painting

  (400-p) = 250 . . . . . hours doing cleanups

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
