The next month, Tamiko develops a budget for her income. One-fourth of her
omeli [17]

Answer:

$79.7

Step-by-step explanation:

Total income is $(234.8 + 64 + 20) = $318.8

Now, One-fourth of her income is budgeted for car insurance i.e. (318.8 \times \frac{1}{4}) = 79.7 dollars.

And, 1/10  of her income is budgeted for gasoline i.e. (318.8 \times \frac{1}{10}) = 31.88 dollars.

Finally, 2/5  of her income is budgeted for savings i.e. (318.8 \times \frac{2}{5}) = 127.52 dollars.

Therefore, the remaining amount of her income = $(318.8 - 79.7 - 31.88 - 127.52) = $79.7 is left for her spending. (Answer)
