She should budget $243.33 for gas if classes start next month and are 4 months long
Spent on gas this month = $50.
Predicted spent of gas next month = $50 * 1.08
Predicted spent of gases for the four months:
$50 * 1.08
$50 * 1.08^2
$50 * 1.08^3
$50 * 1.08^4
Total spent for the four months:
$50 (1.08 + 1.08^2 + 1.08^3 + 1.08^4)
= $50 * (4.8666)
= $243.33,
Hence, the solution is option D. 243.33
Therefore, she should budget $243.33 for gas if classes start next month and are 4 months long
