20y\leq 4800-80y
Use the distributive property to multiply 80 by 60-y.
20y+80y\leq 4800
Add 80y to both sides.
100y\leq 4800
Combine 20y and 80y to get 100y.
y\leq \frac{4800}{100}
Divide both sides by 100. Since 100 is positive, the inequality direction remains the same.
y\leq 48
Divide 4800 by 100 to get 48.
