I need help on this, plz help me solve this

Answer 1

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.
