Answer:
Answer is 60.
Step-by-step explanation:
Two equations, two unknowns.
As you said, let x be the number of $5 items and y the number of $25 items.
First equation is based on VALUE (second sentence):
5x + 25y = 1950
Second equation is based on NUMBER (third sentence):
x + y = 150
Now solve. Easy way is rearrange the second equation (x = 150 - y) and sub into the first:
5(150 - y) + 25y = 1950
750 - 5y + 25y = 1950
20y = 1200
y = 60
Since y represented the number of items sold at $25, 60 is the number of items.
