Answer:
Lara should buy 8 boxes
Step-by-step explanation:
To start we would need to do
72/10
since 72 isn't a multiple of ten we can round it down to 70, then do

7+1=8
3x-2
-(-5x+7)
☝️this is your equation
distribute your subtraction sign to -5x+7 and you get
3x-2
+5x-7
add everything together and you end up with
8x-9
All u gotta do it plug it into ur calculator and you will get a decimal answer
