Answer:
Miles bought 3.4 pounds of jelly beans.
Step-by-step explanation:
Miles spent $13.75 on gummy bears and jelly beans, so to find out how much he spent on jelly beans, we must first find out how much he spent on gummy bears.
Miles bought 2.5 lbs of gummy bears at $3.40/lb, so we should multiply the values to find out how much he spent.
2.5 x 3.4 = 8.5
Since Miles paid $13.75, and $8.50 of that was on gummy bears, he spent $5.25 on jelly beans. Now, we can divide the total cost by the cost/lb to find out how many lbs he bought.
5.25 / 1.5 = 3.5
So, Miles bought 3.5 lbs of jelly beans.
