Answer:
Step-by-step explanation:
Let the number of Noodle Soups = x
Let the chips bring in 0.75 * (123 - x)
Together, the total amount will be 131.25
1.50*x + (123 - x) * 0.75 = 131.25 Remove the brackets on the left
1.50x + 123*0.75 - 0.75*x = 131.25 Combine the left
0.75x + 92.25 = 131.25 Subtract 92.5 from both sides
0.75x = 131.25 - 92.25 Combine the right
0.75x = 39 divide by 0.75
x = 39/0.75
x = 52
Answer
So the school sold 52 Noodle Soups
and 123 - 52 = 71 Hot fries.
