According to the given mixture ratio, Randy needs 2 gallons of oil for every 5 gallons of gas.
To find out how much oil she will need for 8 gallons of gas, we set up a proportion:
2/5 = x/8
Cross-multiplying, we get:
5x = 2 * 8 = 16
Dividing both sides by 5, we find:
x = 16/5 = 3.2
Therefore, Randy will need 3.2 gallons of oil for 8 gallons of gas.
