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

Respuesta :

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

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

Also, she spent $9 on lollipops. It means she spent [tex]15-9= $6[/tex]  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 [tex]\frac{0.75}{6}[/tex] pounds of gummy bears.

Hence, in $6, she can purchase

[tex]\frac{1}{0.75} \times 6\\ \\ =8[/tex]

Therefore, she purchased 8 pounds of gummy bears.
