Answer:
The number of photo albums can be solved using the equation: 1.375n + 5 =60 and n=40 photo albums.
Explanation:
In order to find the number of photo albums, we need to set up an equation to find out how many pounds the crate would weigh with just the albums and divide by the weight of just one album, or 1 3/8. To make it easier to calculate, we can turn 1 3/8 into a decimal of 1.375. Since we know that 1.375 is the weight of each album, we can multiply our variable 'n' by this number. The question also says that the crate itself weighs 5 pounds, so we have to include this weight into our equation as well. If we add 1.375 times 'n' plus the weight of the crate (5 pounds), then we get a total of 60 pounds. When we write it out, it becomes: 1.375n + 5 = 60. To solve for 'n', we need to use inverse operations to subtract 5 from both sides and then divide by 1.375 to get 40 albums.
