Answer:
$76
Step-by-step explanation:
10 guests -----> Costs $9.50
80 guests -----> Costs $9.50 x 8 = $76.00 (because 80 is 8 times 10)
Let Isaac = x
Ruby = x + 4
Svetlana = 4(x + 4)
Together they worked 104 hours, so...
x + x + 4 + 4(x + 4)= 104
x + x + 4 + 4x + 16 = 104
6x + 20= 104
6x = 84
x = 84/6 = 14
Isaac worked x = 14 hours
Ruby worked x + 4 = 18 hours
Svetlana worked 4(x + 4) = 4×18 = 72 hours
Check your answers...
72 + 18 + 14 = 104
104 = 104 it checks!
