A car has a 16 gallon fuel tank and gas mileage of 30 miles per gallon. Write an equation that represents the relationship between the distance the car has traveled in miles (d) and the amount of gas LEFT in the tank .

A.Greg will need  mixed 2 cups of yellow paint with each cup of blue paint.

B. cup of blue paint

C.$9

Step-by-step explanation:

We are given that the ratio of the number of cups of yellow paint to the number of cups of blue paint that Greg mixed to make a shade of green paint is 2:1

A.

Ratio of number of cups of yellow paint to the number of cups of blue paint=2:1

Number of cups of yellow paint =2

Number of blue paint=1

It means Greg will need  2 cups of yellow paint mixed with each cup of blue paint.

B.2 cup of yellow paint  need cup of blue paint =1

1 cup of yellow paint need cup of blue paint=

Hence, the number of blue cups is should Greg add to each cup of yellow paint to make the shade of green.

C.If Greg purchased number of cups of yellow paint =6

Cos of 6 cup=$54

Cost of each cup =$9

Hence, the unit price per cup of yellow paint is $9.
