To raise money for a local charity, students organized a wake-a-thon

where they attempted to stay awake for 24 h. At this event, the

amount of money raised varied directly with the time, in hours, a

participant stayed awake. Tania raised $50 by staying awake for 16 h.

a) Write an equation relating the money Tania raised and the

amount of time, in hours, she stayed awake.

b) How much would she have raised by staying awake for 24 h?

a) T = 3.125h

b) $75

Step-by-step explanation:

Given: We know Tania raised $50 for staying awake 16 hours. We also know the amount of money raised varies directly with the time.

We can divide $50 into 16 hours.

50/16 = 25/8

25/8 = 3.125

3.125 = 3 1/8 (You can use a fraction or decimal, whichever is preferred)

That's how much money she earns per hour. It may not make sense because you have 1/8 of a dollar, so it's okay if you're a little confused on that.

Now let's answer the first question: Write an equation relating the money Tania raised and the amount of time, in hours, she stayed awake.

We know Tania earns $3.125 per hour, so we can make it this equation

T = 3.125h

T can represent Tania's earnings, and 3.125 is how much she earns h, hourly.

Now onto the second question: How much would she have raised by staying awake for 24 h?

We need to multiply 3.125, or 3 1/8, 24 times. Your answer should be $75.
