Question

On a weekend night, a waiter earned $3 an hour and made $45 in tips. He made a total of $60. Write and solve an equation to determine how many hours he worked.

Answer 1

Answer:

The equation to determine the number of hours we worked is $3h+45=60$.

The waiter has worked for 5 hours.

Step-by-step explanation:

Given:

Total Money made = $60

Hourly rate = $3

Money made in tips = $45

We need to find the number of hours he worked.

Solution:

Let the number of hours he worked be 'h'.

Now we can say that;

Total Money he made is equal to sum of Money made in tips and Hourly rate multiplied by number of hours he worked.

framing in equation form we get;

$3h+45=60$

Hence the equation to determine the number of hours we worked is $3h+45=60$.

On Solving equation we get;

First we will subtract both side by 45 we get;

$3h+45-45=60-45\\\\3h=15$

Dividing both side by 3 we get;

$\frac{3h}{3}=\frac{15}{3}\\\\h=5\ hrs.$

Hence the waiter has worked for 5 hours.
