Answer:-2.75 x = -233.75
/ -2.75
x = 85.00
plug value of x in (1)
1.00 x + 1.00 y = 150.00
85.00 + y = 150.00
y = 150.00 -85.00
y = 65.00
y = 65.00
x= 85 number of child tickets
y= 65 number of adult tickets
Step-by-step explanation:x= number of child tickets
y= number of adult tickets
Total sold
1.00 x + 1.00 y = 150.00 .............1
Total value
4.75 x + 7.50 y = 891.25 .............2
Eliminate y
multiply (1)by -7.50
Multiply (2) by 1.00
-7.50 x -7.50 y = -1125.00
4.75 x + 7.50 y = 891.25
$16(4 shirts)= $64
5%=$64(0.05)=$3.20
Jamal's total is $67.20
Answer:
After 460 calls plan 1 is more economical than plan 2
Step-by-step explanation:
Plan 1: 36x + 0y
Plan 2: 13x + 0.05y
36x < 13x + 0.05y
36x - 13x < 0.05y
23x < 0.05y
23/0.05x < y
460x < y
My guess would be -54 because we are starting with -54
