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 situation where x is the number of additional 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.)
