A gas station sells a total of 4500 gallons of regular gas and premium gas in one day. The ratio of gallons of regular gas sold to gallons of premium gas sold is 7 : 2.

a. Write a system of linear equations that represents this situation.

b. How many gallons sold were regular gas? premium gas?

a. System of linear equations that represents this situation is .

b. 3500 gallons of regular gas and 1000 gallons of premium gas was sold.

Step-by-step explanation:

Given:

Total Number of gallons of gas sold =4500 gallons.

The ratio of gallons of regular gas sold to gallons of premium gas sold is 7 : 2.

we need to find the amount of regular gas and premium gas sold in gallons.

Solution:

Let the Multiplicative factor be denoted by 'x'.

So Amount of regular gas sold =

Amount of premium gas sold =

So we can say that;

Total gas sold sold is equal to sum of Amount of regular gas sold and Amount of premium gas sold.

framing in equation form we get;

Hence system of linear equations that represents this situation is .

On Solving the above equation we get;

Dividing both side by 9 we get;

So we can say that;

Amount of regular gas sold =

Amount of premium gas sold =

Hence 3500 gallons of regular gas and 1000 gallons of premium gas was sold.

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
