Answer:
140 coins.
Step-by-step explanation:
Let x be the total number of coins in Kate's collection.
We have been given that Kate has a coin collection. She keeps 7 of the coins in a box which is only 5% of her entire collection.
We need to figure out x such that 5% of x equals to 7. We can represent this information in an equation as:
![\frac{5}{100}*x=7](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B100%7D%2Ax%3D7)
![0.05*x=7](https://tex.z-dn.net/?f=0.05%2Ax%3D7)
![x=\frac{7}{0.05}}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B7%7D%7B0.05%7D%7D)
![x=\frac{700}{5}}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B700%7D%7B5%7D%7D)
![x=140](https://tex.z-dn.net/?f=x%3D140)
Therefore, the total number of coins in Kate's collection is 140 coins.
