A) 6 weeks
B) 7 weeks
C) 8 weeks
D) 9 weeks

Answer 1

To determine how many weeks Thom needs to save for the laptop, subtract his current savings from the laptop's cost, and then divide the result by his weekly savings. Rounding up to the nearest whole week, it will take Thom 7 weeks.

Step-by-step explanation:

Thom is currently saving to buy a laptop, and we need to calculate how many weeks it will take him to save enough money. Thom has an initial amount of $178.90, and he can save $79.00 each week. The cost of the laptop is $719.50. To find out how many weeks it will take, we follow these steps:

1. Subtract the initial amount Thom has from the total cost of the laptop: $719.50 - $178.90 = $540.60.
2. Divide the remaining amount by the weekly savings: $540.60 ÷ $79.00 ≈ 6.84.
3. Since Thom can only save for whole weeks, we round up the result to the next whole number, which is 7.

Therefore, it will take Thom 7 weeks to have enough money to buy the laptop. The correct answer is B) 7 weeks.
