Answer:
0 T, 4 D
1 T, 3 D
2T, 3D
3T, 2D
4T, 1D
5T, 1D
Step-by-step explanation:
So let's start with what we know!
Gift certificate = $100
T-shirts = $15 each
Dress shirts = $22 each
You need to buy at least one dress shirt in the process and at least spend $90
You can simply find the combinations by going in desmos and writing in:
15x + 22y <= 100
y > 1
15x + 22y >= 90
Find the combinations by looking at the integer values of x, and using only the integer values of y ( do not round them, just cut them down to the integer). Look where all the regions are shaded
The possible combinations are as follows
Note: I am going to initial t-shirts to T and dress shirts to D
0 T, 4 D
1 T, 3 D
2T, 3D
3T, 2D
4T, 1D
5T, 1D
