Define variables as x = number of crayons and x + 2 = number of notebooks
To find out how much she spent, we subtract her change from what she paid with: 10.00 – 1.05 = 8.95
Then we need to solve the problem cost of notebooks plus the cost of crayons equals the total cost.
1.25(x + 2) + 0.90x = 8.95 and solving for x gives 3 crayons and 5 notebooks

We ignore the decimals for the time being, multiplying:
Since, between them, the two original factors have a total of two digits to the right of their decimal points, we place the decimal point in the product so that there are two digits to the right. This yields:
