Step-by-step explanation:
Answer:
$68.97
Step-by-step explanation:
The equation you have to use is I=p(1.45)
If you have a 45% increase to 100, the original price was $68.97.
For this case we have that the variable "x" represents the number of hours that Leticia uses to take care of children on Saturday.
IF on Friday I use 4 hours ($ 8 each) and on Saturday "x" hours ($ 8 each) obtaining a profit of $ 72, we have the following equation:
![8 (4 + x) = 72](https://tex.z-dn.net/?f=8%20%284%20%2B%20x%29%20%3D%2072)
We apply distributive property:
![32 + 8x = 72\\8x = 72-32\\8x = 40\\x = \frac {40} {8}\\x = 5](https://tex.z-dn.net/?f=32%20%2B%208x%20%3D%2072%5C%5C8x%20%3D%2072-32%5C%5C8x%20%3D%2040%5C%5Cx%20%3D%20%5Cfrac%20%7B40%7D%20%7B8%7D%5C%5Cx%20%3D%205)
So, on Saturday she spent 5 hours.
