For the 10 gallons and car wash, she would pay ($2/gallon)*(10 gallons) + ($0/car wash) = $20.00

If in planning her retirement liza deposits some money at 3% interest, with twice as much deposited at 4.5%. The amount deposited at each of the total annual interest is: $14,000 is invested at 4% and $28,000 is invested at 4.5%.
<h3>Amount deposited</h3>
Let x represent amount deposited at 3%
Let 2x represent the amount deposited at 4.5%
Hence:
.03x + .045(2x) = $1680
.12x = $1680
Divide both side by .12x
x=$1680/.12
x = $14,000 at 3%
So,
2x= $14,000
x=2×14,000
x=$28,000 at 4.5%
Therefore the amount deposited at each of the total annual interest is: $14,000 is invested at 4% and $28,000 is invested at 4.5%.
