To find the number of boxes of granola bars the father bought, we can set up the equation:
16 + 4x = 36
Subtracting 16 from both sides:
4x = 20
Dividing both sides by 4:
x = 5
Therefore, the father bought 5 boxes of granola bars.
If the boxes have 5 bars in each, the equation would be:
16 + 5x = 36
Subtracting 16 from both sides:
5x = 20
Dividing both sides by 5:
x = 4
Therefore, the father bought 4 boxes of granola bars.
For the total number of granola bars in the cupboard if each box had 10 bars, the expression is:
g = c + 10x
The general equation to calculate the total number of granola bars in the cupboard after the father goes to the store would be:
g = c + bx
