y= 450x
Step-by-step explanation:
Given data
Let y represent the total amount of money
Let x represent the number of home runs
For each run they donate $450
We can model this situation as
y= 450x
Answer: let's say x = 1
16 x 1 =16
16+20=36
36x1/2=18
Step-by-step explanation:
-3(x+5)=-9
-3x-15=-9
+15 +15
-3x=6
-1x=2
1x=-2
x=-2
$60 for 2 hours and $100 in total for 2 hours of work and the service fee
