Question

Drag each number to the correct location on the equations. Each number can be used more than once, but not all numbers will be used. Roy and Elisa are buying tickets for the annual school concert. Roy buys 6 adult tickets and 2 child tickets for a total of $66. Elisa buys 5 adult tickets and 4 child tickets for a total of $62. Determine the system of equations that can be used to find the cost of one adult ticket, a, and the cost of one child ticket, c. 66 62 5 2 8 128 4 6

Answer 1

first answer is right trust that one.

Explanation:

Answer 2

a=$10

c=$3

Explanation:

Step one:

given data

let adults tickets be a

and child tickets be c

so

Roy's purchase

6a+2c=66------1

Elisa's purchase

5a+4c=62-------2

Hence, the system of equations

6a+2c=66------1

5a+4c=62-------2

solving simultaneously

6a+2c=66------1 x2

5a+4c=62-------2 x1

12a+4c=132

-5a+4c=62

7a=70

divide both sides by 7

a=$10

put a=70 in 1

6(10)+2c=66------1

60+2c=66

2c=66-60

2c=6

c=$3
