Question

An amusement park sells adult tickets with adults costing $5 and children's costing $3. If Ed bought 15 tickets and spent a total of $57 dollars how many tickets did he buy

Answer 1

Answer:

The answer is x=9

Step-by-step explanation:

y = adult tickets

x = children tickets

----------------------------------

x + y = 15

3x + 5y = 57

----------------------------------

-3x - 3y = -45

3x + 5y = 57

----------------------------------

2y = 12

----------------------------------

y = 6

----------------------------------

x + 6 = 15

----------------------------------

x = 9
