Answer:
$31.16
Step-by-step explanation:
Last week, Chen bought 8 1/2 gallons at the rate of $2.30 per gallon.
This week, he bought 4 3/10 gallons at the rate of $2.70 per gallon.
The total cost = 8 1/2*2.3 + 4 3/10*2.7
Convert the mixed fraction to improper fraction.
= 17/2 *2.3 + 43/10 *2.7
= $19.55 + $11.61
= $31.16
The total cost was $31.16
Thank you.
Answer:$13504.6
Step-by-step explanation:
See last week Chen bought 812 gallons of gas at $2.30 per gallon.
So, total cost = 812*2.30
= $1867.6
This week Chen bought 4310 gallons of gas at $2.70 per gallon.
So, total cost = 4310*2.70
= $11637
To find Total Cost for both weeks , we have to sum up the cost of the respective weeks.
So Total Cost = $1867.6 + $11637
= $13504.6
Hope it helps!!!
