20 units im shure i took the test'
That was made up?cz I tried to solve it and I kept getting different #s
Well Zack's cost more because, he paid $567.00 for whatever he bought, while Mal paid $245.00 for whatever he bought.
First we will do -3 times everything in the parenthesis.
-3 times -4n = 12n
-3 times 30 = -90
SO,
12n - 90 = -30
+90 +90
12n = 60
divide 12 on both sides;
n = 5
This is your answer,
IF THIS HELPED, PLS GIVE ME BRAINLIEST!
