$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.

$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
