Work Shown

1/4 + 1/5 = 5/20 + 4/20 = 9/20

Ryan spent 9/20 of his monthly salary on rent and utilities combined.

This means he keeps the remaining 11/20 of his monthly salary.

Think of Ryan and his friends eating 9 pieces of cake, out of 20 pieces total. That must mean there are 20-9 = 11 pieces left over.

So,

x = monthly salary

(11/20)x = 1342 dollars remain

11x = 20*1342

11x = 26840

x = 26840/11

x = 2440
