Set up a proportion
42.50/5=x/8
5x=340
x=68
He would earn $68
Let m and s be the number of math and sociology books sold respectively.
m=s+88 we are also told that:
m+s=426, using m found above in this equation gives you:
s+88+s=426 combine like terms on left side
2s+88=426 subtract 88 from both sides
2s=338 divide both sides by 2
s=169, since m=s+88
m=169+88=257
So 257 math and 169 sociology textbooks were sold.
Answer: 12.69 miles approx
Step-by-step explanation:
let x represent the number of miles traveled

x = 12.69 miles approx
Tan(12) = 40/d
d = 40/tan(12)
d = 188.19m
