Kate has a coin collection. She keeps 7 of the coins in her box, which is only 5% of her entire collection. What is the total number of coins in Kate's coin collection?

140 coins

Step-by-step explanation:

To calculate the total number of coins Kate have in her collection, we can use the rule of three:

The problem says that 7 of her coins are equivalent of 5% of her entire collection, and we want to know the total number of coins (100%) of her collection. So, if 7 coins are 5%, how much coins are 100%:

7 -> 5%

X -> 100%

7/X = 5/100

X = 100*7/5 = 140 coins

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
