Write the inequality (without solving)
Lesechka [4]

Answer:

2.15f+4.6n\leq 150

Step-by-step explanation:

She has a budget of $150, which means that she can spend no more than that amount. Therefore, use the less than or equal to symbol: ≤

Each folder is $2.15, so you are going to multiply: 2.15 × f

Each notebook is $4.60, so you will multiply: 4.6 × n

You want to know how many notebooks and folders you can buy for $150, so add the notebooks and folders.

Make the equation:

2.15f+4.6n\leq 150

:Done

long way

12 x 11 x 10 x 9 x 8 x 7 x6 x5 x4 x3x2/ 10x9x8x7x6x5x4x3x2x


but you can shorten that by crossing out identical numbers so you get 12 x 11

12 x 11 = 132 combinations
