Question

Penelope is raising money for a school trip by selling candy bars and lollipops. The price of each candy bar is $2 and the price of each lollipop is $1. Yesterday Penelope made $43 from selling a total of 30 candy bars and lollipops. Determine the number of candy bars sold and the number of lollipops sold.

Answer 1

Answer:

number of candy bar=13

number of lollipops=17

Step-by-step explanation:

no of lollipops = x;  no of candy bars=y

2y+x=43;

x+y=30;

solving two equations y=13, x=17

Answer 2

The number of candy bars sold and the number of lollipops sold are 13 and 17 respectively.

Step-by-step explanation:

Let x be the no. of candy bars and y be the no. of lollipops

Price of 1 candy bar = $2

Price of x candy bar = 2x

Price of 1 lollipop = $1

Price of y lollipop = y

Penelope made $43 from selling a total of 30 candy bars

So, x+y = 30 -- A

2x+y = 43 --B

Substitute the value of x from A in B

2(30-y)+y = 43

60-2y+y = 43

60-43 = y

17=y

Substitute the value of y in A

x+17 = 30

x = 13

Hence the number of candy bars sold and the number of lollipops sold are 13 and 17 respectively.
