Question

For his birthday, Kyle receives 40 dollars from his arm every day after he receives a dollar and twenty-five cents to put in his savings. After how many days will Kyle have saved mom 100 dollars? Write the equation.

Answer 1

The equation that represents the situation is 40d + 1.25d = 100. It will take Kyle approximately 3 days to save $100 for his mom.

Step-by-step explanation:

The equation that represents this situation can be written as:

40d + 1.25d = 100

Where 'd' represents the number of days.

To solve the equation, you need to combine like terms:

41.25d = 100

Next, divide both sides of the equation by 41.25 to isolate 'd':

d = 100/41.25

Using a calculator, you will find that:

d ≈ 2.42

Rounding up to the nearest whole number, Kyle will have saved $100 for his mom after approximately 3 days.
