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, 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?

Respuesta :

Answer:

9

Step-by-step explanation:

Given that

Spending done by Miranda each time while go to the store = $7

Spending done by Savannah each time while go to the store = $9

For computing the least possible number we need to take the least common multiple of $7 and $9 i.e to be $63

Now the lease possible number for Miranda has been to the store is

[tex]= \frac{ Lease\ common\ multiple}{Spending\ done \ by\ miranda}[/tex]

[tex]= \frac{\$63}{\$7}[/tex]

= 9

Or we can do one thing as we know that 7 is a prime number which is not cut by any other number except one while the 9 factor could be [tex]= 3\times 3[/tex]

Therefore the 9 times would be considered
