Answer:
4s + g = 76.00
4(9)+ g=76.00
36+g=76.00
36-36+g=76-36
g=40 /4
g=10
Step-by-step explanation:
106.00-30=76.00
s= shoes 9.00
g= games
4s + g = 76.00
4(9)+ g=76.00
36+g=76.00
36-36+g=76-36
g=40 /4
g=10
Step-by-step explanation:
1. 3:1
2. 12:4
3. 15 : 3

We have two formulas:
Adult tickets plus Student tickets = 550 tickets or A + S = 550
and
Adult tickets times $20 plus Student ticket times $10 = $7500 or
(A * 20) + (S * 10) = 7500
First let's get rid of one of the variables by re-balancing the simplest formula
A+S = 550
A+S-A = 550-A
S = 550-A
Now we can restate the second formula replacing "S" with it's equivalent "550-A"
(A * 20) + (S * 10) = 7500
(A * 20) + ((550-A) *10) = 7500
Then do the multiplication
20A + 5500 - 10A = 7500
and simplifiy
20A + 5500 - 5500 - 10A = 7500 - 5500
20A - 10A = 2000
10A = 2000
A = 200
S = 550 - 200 = 350
Now we should test the answers to be sure our work
is correct:
200 Adult tickets times $20 = $4000
350 Student tickets times $10 = $3500
$4000 + $3500 = 7500
