Question

Miranda and Savannah are excited that a new store just opened in town! They go together the first day it opens! Each time Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9.A few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.

Answer 1

Miranda made 9 visits to the store and Savannah made 7 visits to the store

Explanation:

To find how many times Miranda and Savannah went to the store we would need to find the Greatest Common Multiple of the amount that each of them spends per visit. We do this by simply going through each of these numbers' times tables until we find a common one.

7 * 1 = 7 9 * 1 = 9

7 * 2 = 14 9 * 2 = 18

7 * 3 = 21 9 * 3 = 27

7 * 4 = 28 9 * 4 = 36

7 * 5 = 35 9 * 5 = 45

7 * 6 = 42 9 * 6 = 54

7 * 7 = 49 9 * 7 = 63

7 * 8 = 56

7 * 9 = 63

Finally, we can see that the first time that both Miranda and Savannah have spent the exact same amount would be when Miranda made 9 visits to the store and Savannah made 7 visits to the store. Each of which wasted $63
