Answer:
50
Step-by-step explanation:
2,500/50=50
50x50=2,500
The first thing we must do for this case is to define variables.
We have then:
x = cost of a hardcover book
y = cost of a paperback book
We write the system of equations:
3x + 7y = 29.50
2x + 5y = 20.50
The solution to the system is:
x = 4 $
y = 2.5 $
Answer:
the cost of a hardcover book is $ 4
$2.80 but if rounded to the nearest penny that would be $3.00. Hope this helps!
