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
