Question

There are nine water bottles in​ Devin's refrigerator. He adds three full boxes of water bottles to the refrigerator. Then he adds two more boxes that each has 1 fewer bottle than a full box. When he is​ done, there are 67 bottles in the refrigerator. Write and solve an equation to find the number of bottles in a full box.
Write the equation

Answer 1

Answer: there are 12 bottles of water in each box.

Step-by-step explanation: 12+12+12+11+11+9 = 67

Answer 2

The number of bottles in the full box by solving the equation is 12.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the number of bottles in the full box = x

Initial bottles = 9

Bottles in 3 full box = 3x

Bottles in 2 box in which number of bottles is x - 1 = 2(x-1)

Now,

Total bottles in refrigerator is 67

So,

9 + 3x + 2(x - 1) = 67

9 + 3x + 2x - 2 = 67

5x = 60

x = 12

Hence "The number of bottles in the full box by solving the equation is 12".
