pls give me brainliest
Let x be the number of $5 items sold.
Let y be the number of $25 items sold.
x + y = 150
x = 150 - y .........(1)
5x + 25y = 1950 ......(2)
Plugging the expression for x from (1) into (2), we get:
5(150 - y) + 25y = 1950
750 - 5y + 25y = 1950
20y = 1200
y = 60 items.
The answer is, there were 60 items sold at $25.
