kupik [55]

Answer:

Total selling price= $663.82

Selling price per liter= $1.69

Step-by-step explanation:

Giving the following information:

Proportion of oil and gasoline:

Oil= 3/14= 0.21

Gasoline= 11/14= 0.79

The oil costs $0.75 per liter.

The gasoline costs $1.60 per liter.

<u>First, we need to calculate the number of liters of oil and gasoline required:</u>

<u></u>

Oil= 0.21*392= 82.32 liters

Gasoline= 0.79*392= 309.68

<u>Now, the total cost to produce 392 liters:</u>

Total cost= 82.32*0.75 + 309.68*1.6

Total cost= $577.23

<u>Finally, the total and unitary selling price:</u>

Total selling price= 577.23*1.15= $663.82

Selling price per liter= 663.82 / 392= $1.69

Basically what you do is                             (the ^ arrow meaning exponent)
You take 3.7 + 4.45 x 10^20
Then 8.15 x 10^20, remove the decimal of 8.15 = 815 x 10^-2 x 10^20
815 x 10^18 = <span>815000000000000000000</span>
