Mary is making ice cubes with fruit frozen in them for a cocktail party. She makes some strawberry cubes, and a number of blueberry cubes equal to 5 times the number of strawberry cubes minus 4. If she makes 116 ice cubes total, how many blueberry cubes does she make?

Define a variable ** Let s be the number of strawberry cubes and b be the number of blueberry cubes. We know that b = 5s - 4 and s + b = 116.
Write an equation ** Substituting the first equation into the second, we get s + 5s - 4 = 116.
Combine like terms ** Combining like terms, we get 6s - 4 = 116
Add 4 to both sides ** Adding 4 to both sides, we get 6s = 120
Divide by 6 ** Dividing both sides by 6, we get s = 20
How many blueberry cubes does Mary make? ** Substituting this value back into the equation b = 5s - 4, we get b = 96
#### 96
