Susana=s
maria=m
m= 3s/5
s+m=56
s+(3s/5)=56
(5s+3s)/5=56
8s=56*5
8s=280
s=280/8
s=35
35 --->5/5
x ---> 3/5
x= (3/5)*35 / (5/5)
x=21

Answer: $266,000
Explanation: $256,000 + $10,000 = $266,000
Answer:
Step-by-step explanation:
Each package holds 24 so you would use the equation n = 24p
which means the number of lightbulbs = 24 times the number of packages
so 1 package = 24
3 packages = 72
10 packages = 240
oh and part B is B
Step-by-step explanation:
<u>to show how many tickets were sold:</u>
x = upper floor tickets
y = main floor tickets
x + y = 2000
<u>to show total amount of revenue:</u>
25x + 40y = 62,000
<u>Finding answer using both equations:</u>
x + y = 2000
multiply each side by 25
25x + 25y = 2000 × 25
25x + 25y = 50,000
25x + 40y = 62,000
-
25x + 25y = 50,000
-----------------------------------
15y = 12,000
^ this is column subtraction
<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>
15y = 12,000
divide each side by 15
12,000 ÷ 15 = 800
y = 800
x + y = 2000
x + 800 = 2000
x = 1200
Therefore 1200 upper-level tickets were sold
800 main floor tickets were sold
