a group of children walk to a corner store and buy cans of soda for a total of $3.36 and candy bars for a total of $2.45.
Each child has one can of soda and one candy bar.
How many children were in the group> What is the cost of one can of soda and one candy bar?
:
Lets do this in cents, 336 and 245
Find the common prime factors
336: 2*2*2*2*3*7
245: 5*7*7
:
The common factor is 7, therefore: 7 children in the group
:
336/7 = 48 cents for a soda
245/7 = 35 cents for a candy bar
