Kendra and Jeremy bought 10 gallons of gasoline at $3.26 per gallon. How much did Kendra and Jeremy pay for the gasoline?

They payed $32.05 bec 3.25 times 10 = 32.6

If you have questions like this, you have to multiply the number of things that are bought by their prize per things:

so here the number is 10 gallons, and the prize is 3.26 per gallon.

and the answer is 10*3.26, which is 32.6 (multiplying fractions by 10 means "moving" the perdioD by 1 to the right, a tip!)
