C 11

D 13

E 17

Answer 1

Option C

Explanation:

We are given that Sheila purchase candy and bars of chocolates.

We have to find the number of bags of cotton candy and bars of chocolate

Cost of one cotton candy bag =$0.70

Cost of one bar chocolate bag =$0.50

She have total money for spent=$6.30

Let x be the number of bags of cotton candy and y be the number of bags of bars of chocolates

Then

`0.70x+0.50y=6.30`

If she purchase 5 bags of cotton candy

Then she spend money on cotton candy bags=
`0.70*5=`$3.50

Substitute the value then we get

`3.50+0.50y=6.30`

`0.50 y=6.30-3.50`

`x=(3.00)/(0.50)`

`x=6`

Number of bags of cotton candy=5

Number of bags of bar of chocolates=6

Then total number of bags=6+5=11

Hence, option C is true.
