emmainna [20.7K]

Answer:

$550

Step-by-step explanation:

In this question, we have to find how much a party would cost for 80 people.

We know that our equation is C = 6.50x + 30

"x" is the amount of people.

To found our answer, we would plug in 80 to "x" to find the total cost.

Solve:

C = 6.50(80) + 30

C = 520 + 30

C = 550

This means that the cost of the party for 80 people would be $550.

Joe earns $425 a week for working 40 hours and an additional $20 an hour for each hour over 40. Last week, Joe made $485. Write
Tasya [4]

Answer:

Joe worked 3 hours overtime.

Step-by-step explanation:

Let t = number of hours overworked

425 + 20 × t = 485

425 + 20t = 485

20t = 485 - 425

     = 60

\frac{20t}{20} = \frac{60}{20}

t = 3

\therefore Joe worked 3 hours over time.

Hope this helps :)
