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 $7 dollar sign, 7, and each time Savannah goes to the store she plans to spend $9 dollar sign, 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. What is the least possible number of times that Miranda has been to the store?

Answer 1

Here we have to find the LCM of 9 and 7

LCM(9,7) = 63

So 63 will be the total amount paid by each.

number of times MIranda has been to the house = 63/7=9 

Answer 2

Answer:

63

Step-by-step explanation:

Given :Each time Miranda goes to the store she plans to spend $7

          Each time Savannah goes to the store she plans to spend $9

To Find : What is the least possible number of times that Miranda has been to the store?

Solution:

We are given that  Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.

So, we are supposed to find the LCM of 9 and 7

3 |  9,7

3 | 3 ,7

7 | 1,7

  | 1 ,1

LCM = $3 \times 3 \times 7$

LCM = 63

Hence the least possible number of times that Miranda has been to the store is 63.
