What's a real-world problem that can be modeled by the equation 1.25 = 0.75x + 50 ?

4 0

Well, you could say that you want to buy something for $1.25. Like a game or a toy or something! So you need to have $1.25 in order to get this item. You have $50 in your savings account you make 0.75 an hour. And then x would represent the number of hours you have to work. It doesn't really make sense since if you have 50$ in your savings account then you would be able to buy it automatically but, for the sake of this let's just pretend! I'm pretty sure this example will work! Hope it helped!

Kali spent half of her weekly allowance on clothes. To earn more money her parents let her clean the gutters for $9. What is her

So to find the answer to this, you have to consider that $\frac{1}{2} x + 9 = 13$ - half because half the pocket money (x) was spend on clothes, then plus 9 because that's how much extra she gained and 13 because that was the result of all the changes.

To solve this, first subtract 9 from both side, which leaves you with $\frac{1}{2} x = 4$ and $\frac{1}{2} x$ is the same as $\frac{1x}{2}$ , so to solve this, multiply both sides of the equation by two, resulting in $x = 8$ . SO from this we can conclude that the weekly allowance is $8
