Answer:

Step-by-step explanation:

Carissa spent $50 on gas this month, and the gas prices are predicted to increase 8% every month for the next six months. This can be expressed as a geometric sequence with the first term being $50 and the common ratio being 1.08.

Thus, the total amount that Carissa would spend on gas for the next four months can be calculated as:

$50 + $50(1.08) + $50(1.08)^2 + $50(1.08)^3 = $210.80 (rounded to the nearest cent)

Therefore, Carissa should budget $210.80 for gas for the next four months.
