Answer: 35 snickers candies
Total number of candy bars in a box = 84
The ratio of snickers to twix bars is 5 to 7
let the number of candy = x
Using a common variable formula
Let the number of snickers = 5x
Let the number of twix bars = 7x
Since, the sum of snickers and twix bars = 84
Therefore,
5x + 7x = 84
12x = 84
Divide both sides by 12
12x/12 = 84/12
x = 7
Since, snickers = 5x
Total number of snickers = 5 x7
Total number of snickers = 35
Therefore, we have 35 snickers candies in the box
