Answer:
$36
Step-by-step explanation:
ok so first you want to find out how much she makes per hour and to do that you would take $27 / 3hrs = $9. So now we know that Kayla makes $9 per hour. If she babysits for 4 hours you would then do $9 x 4hr = $36.
If the first one is a = 180 - b, and not 180 - 6, then that is correct.
Also, 360 = 2a + 2b is correct
