Problema Solution
A waiter earns a salary of $500 per month for working 4 hours a day. In May, he worked additional hours at $10 per hour and earned $650 for the month. Write an equation to model this situatioin where "x" is the number of additonal hours he worked in May. Find the additional number of hours he worked in May.
Answer provided by our tutors
10x + 500 = 650 (10 times the number of hours plus the monthly salary equals $650.)
10x = 650 - 500 (Subtract 500 from both sides to begin to isolate your variable.)
10x = 150 (Now divide by 10.)
x = 15 (The waiter worked 15 additional hours.)
