231.25 miles

Step-by-step explanation:

0.75*19+0.75*18+0.75*17+0.75*16+0.75*14+0.75*13+0.75*12+0.75*11+0.75*10+0.75*9+0.75*8+0.75*7+0.75*6+0.75*5+0.75*4+0.75*3+0.75*2+0.75*1=131.25

5*20+131.25=100+131.25=231.25

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
