jimmy earns $7.50 per hour. how long will it take him to earn $150? What is the equation to solve this problem?

Answers

Answer:

$150 = $7.50/hour × t

Step-by-step explanation:

To determine how long it will take Jimmy to earn $150 at a rate of $7.50 per hour, you can set up an equation.

Let "t" represent the number of hours it will take Jimmy to earn $150.

The equation for this situation is:

Earnings = Rate × Time

In this case,

Earnings is $150, Rate is $7.50 per hour, and Time is "t" hours.

So, the equation becomes:

$150 = $7.50/hour × t

Now, you need to solve for "t." To do that, you can divide both sides of the equation by $7.50/hour to isolate "t":

t = $150 / ($7.50/hour)

t = 20 hours

So, it will take Jimmy 20 hours to earn $150 at a rate of $7.50 per hour.

Answer:

7.50x = 150

Step-by-step explanation:

7.50x = 150

x = 150/7.50

x = 20 hours
