Answer:
30
Step-by-step explanation:
you divide 20 by 4 then multiply that by 6
These are what you can plot:
(-2, 0.444), (-1, 0.667), (0,1), (1, 1.5,), (2,2.25)
100% - 30% = 70%
The shirt is selling for 70% of the original price.
Multiply the original price by 70%
26.98 x 0.70 = 18.89
The sale price is $18.89
