Answer: The percent changed because it increased by 180%.
Step-by-step explanation:
Evaluate the left hand side first:
![4\cdot 45 + 3r = 180+3r](https://tex.z-dn.net/?f=%204%5Ccdot%2045%20%2B%203r%20%3D%20180%2B3r%20)
So, the equation is
![180+3r =336](https://tex.z-dn.net/?f=%20180%2B3r%20%3D336)
Subtract 180 from both sides:
![3r = 336-180 = 156](https://tex.z-dn.net/?f=%203r%20%3D%20336-180%20%3D%20156%20)
Finally, divide both sides by 3:
![r = \dfrac{156}{3} = 52](https://tex.z-dn.net/?f=%20r%20%3D%20%5Cdfrac%7B156%7D%7B3%7D%20%3D%2052%20)
