Question

Monica is shopping for candy for her wedding and needs lollipops and gummy bears for a display she is making for the reception. Lollipops are $1 per pound and gummy bears are $0.75 per pound. She knows she wants to spend exactly $15 on candy. If she spent $9 on lollipops, which of the following is the number of pounds of gummy bears she purchased?

6 8 9 12

Answer 1

the answer is 8 because 8 times .75 is 6 and 6 plus 9 equals 15

Answer 2

We have been given that she wants to spend exactly $15 on candy.

Also, she spent $9 on lollipops. It means she spent
`15-9= $6` on gummy bears.

Also, we have been given that the cost of gummy bears are $0.75 per pound.

Thus, in 1$ she can purchase
`(0.75)/(6)` pounds of gummy bears.

Hence, in $6, she can purchase

`(1)/(0.75) * 6\\ \\ =8`

Therefore, she purchased 8 pounds of gummy bears.
