1000 tickets were bought at a concert. the amount needed to buy a children’s ticket was $4.50 and the amount needed for an adult
Sholpan [36]

Answer:

The number of children's tickets bought was 300 and the number of adult tickets bought was 700

Step-by-step explanation:

Let

x ----> the number of children's tickets bought

y ----> the number of adult tickets bought

we know that

x+y=1,000

x=1,000-y -----> equation A

4.50x+8.50y=7,300 -----> equation B

Solve the system by substitution

substitute equation A in equation B

4.50(1,000-y)+8.50y=7,300

solve for x

4,500-4.50y+8.50y=7,300

4y=7,300-4,500

4y=2,800

y=700

<em>Find the value of x</em>

x=1,000-700=300

therefore

The number of children's tickets bought was 300 and the number of adult tickets bought was 700

anastassius [24]

Answer:

$ 21

Step-by-step explanation:

Money spent = (2/5) * 60 + (1/4) * 60

                      = 2*12 + 1*15

                      = 24 + 15

                      = $ 39

Money save = 60 - 39 = $ 21
