Apaint store has 35 gallons of paint in the storage, 2/5 of which are for outdoor use. the others are for indoor use. if each gallon costs $22, what is the total cost of the indoor paint

1.)So first find out how many outdoor gallons of paint there are out of 35 gallons.
-Change the fraction 2/5 to the actual amount of outdoor paint to the total
amount of gallons of paint.
- To do that multiply the top and bottom of the fraction by 7 because 5×7=35.
- The top number will then be the actual amount of outdoor paint out of 35.

2.) Find out how many gallons there are of indoor paint out of the 35 gallons.
- Subtract the top number (the amount of gallons of outdoor paint) from the
35 gallons.
-Since you done that, you now know how many gallons of indoor paint you
have.

3.) You now have to find the total cost of the total amount of gallons of indoor
paint.
- Multiply the total amount of gallons of indoor paint ×$22

I hope you understand my explanation and I hope I helped you :)

The correct answer will be d. -4
