For every $20 that carlin saves, his grandmother gives him $30. what is the constant of proportionality? if carlin saves $150, how much money will his grandmother give him?

it 2

step-by-step explanation:

8^1/3=2

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
