She has to buy both binders and notebooks. So, you have to take into account that she has to have both. The closest you can get to $20 while still getting notebooks, is to buy 4 binders. 4 times 4 equals 16. So, she can get 4 binders and 2 notebooks, because then, 2 times 2 equals 4 and 16 plus 4 equals 20.
The gratest number of binders that Eula could buy are 5 binders.
Step-by-step explanation:
Take into account that the inequality the variable x represent binders and the variable y notebooks.For doing this we will solve the inequality for x:
4x+2y ≤ 20
4x ≤ 20 -2y
x ≤ (20 -2y)/4
Now we try with any couple of integer value for y that satisfy the equation. Since we must find out the greater amount of binders Eula could buy then we can try first without notebooks:
x ≤ (20 -2.0)/4
x ≤ 20/4
x ≤ 5
As 5 is an integer and x can take this value, we say that 5 is a possible numbers of binders to buy.
Look at how many field goals were actually made and order them from least to greatest- 12, 15, 19. They are already listed from least to greatest in the table.
