Answer:
1. $132.24
2. $55.89
3. $1336.66
4. $258.19
5. $57.86
Step-by-step explanation:
Simply use this equation.
Substitute in our values, using No.1 as our example.
Cross multiply
922.575 = x100
Solve for x by dividing by 100.
x = 9.22575
Now add x to the initial value.
9.22575 + 123.01 = 132.23575
Round to the nearest hundredth for the answer.
$132.24
