Question

Gregg needs to buy gas and oil for his car. Gas cost $3.85 a gallon and oil costs $6.41 a quart. He has $65 to spend. Write an inequality to represent the situation, where g is the number of gallons of gas he buys and q is the number of quarts of oil

Answer 1

The equation is:
3.85g + 6.42q = 65

The reason why it looks like that is because he spent $65 in total. And it’s $3.85 per one gallon and $6.41 per one quart.
