Question

Bob wants to buy a TV that cost $500 plus 8% tax. He is getting a bonus of $45 and a birthday gift of $85 which he plans to use to help but the TV. He also has to pay 2 bills for $35 each. If Bob makes $12 an hour how many whole hours will he need to work to make enough money to buy the TV and pay his bills?

Answer 1

40 hours.

Explanation:

Cost of TV = $540

(8/100) x 500

Breaking down further,

(2/25) x 500= 1000/25= $40

Therefore, the cost of the TV is $500 + $40= $540

Bonus= $45

Birthday gift= $85

Total income = $130

Bills= $35 x 2 = $70

Total expenses= $70

Net income= $130 - $70 = $60

Remember, TV costs $540

So, $540 - $60 = $480.

If Bill makes $12 an hour, how many hours will he have to work to pay for $480?

= $480/$12= 40 hours.

Answer 2

He needs to work for 40 whole hours

Explanation:

In this question, we are tasked with calculating the amount a Tv will cost Bob in terms of the number of hours he needs to work.

Let’s look at the total cost he has to pay.

a. $500

b. 8% tax = 8/100 * 500 = $40

c. He is paying 2 bills of $35 each making a total of 2 * $35 = $70

The total amount he is to pay is thus; 500 + 40 + 70 = $610

Let’s look at his income ;

a. Bonus $45

b. Birthday gift $85

The total amount of money he has asides his salary to offset the bill is 45 + 85 = $130

The balance to pay from his salary would be $610 - $130 = $480

The number of hours he has to work since he earns $12 per hour would be 480/12 = 40 hours of work
