Question

Write an equation for each word problem. Then solve.

Answer 1

1: (72-57)/3=5

2:(2,150-1,800)/35=10 those are the answers

Answer 2

1.

Let w be the number of weeks it takes for Konrad to have more than $72.

The equation we can derive is 57 + 3w > 72.

Then solve:

57 + 3w > 72

3w > 15

w > 5

Then w must be 6, which is the next number greater than 5.

2.

Let w be the number of weeks it takes Omar to have enough money for the car.

The equation we can derive is 1800 + 35w $\geq$ 2150.

Then solve:

1800 + 35w $\geq$ 2150

35w $\geq$ 350

w $\geq$ 10

Then w must be 10.
