-4x/5+8.8. I think that's it, and if it isn't, i don't know.
Each month the new total you be
initial amount * 1.024
Repeating the process for a year (=12 months) you get
initial amount * 1.024^12
Being initial amount = $100
100*1.024^12 = $132.92
After 1 year you will have $132.92
154 + 74 = 228 is the answer.
