Answer:
Number of children tickets sol= 580
Number of adults tickets sol= 420
Step-by-step explanation:
<u>First, we establish a system of equations:</u>
1.5*x + 4*y= $2,550
x + y = 1,000
x= number of tickets for children sold
y= number of tickets for adults sold
<u>Now, we determine the value of x in one equation and substitute in the other:</u>
x= 1,000 - y
1.5*(1,000 - y) + 4y = 2,550
1,500 - 1.5y + 4y = 2,550
2.5y = 1,050
y= 420
x= 1,000 - 420
x= 580
Number of children tickets sol= 580
Number of adults tickets sol= 420
<u>Prove:</u>
1.5*580 + 4*420= $2,550
580 + 420 = 1,000
