Why did some private american companies decide to build roads?

a) private companies received federal money to build the roads.

b) private companies did not build roads.

c) private companies wanted to provide free roads that would enable more settlers to move west.

d) private american companies knew they could make a profit by charging travelers for using the roads.

I want to say its D.

I'm not 100% sure, A is true, but may not be correct answer for this question. B for sure is incorrect because they did build roads. And C is incorrect because they did not let them go for free. So I would either guess A, or D.

D is right!

Hope this helps! ;)

for many centuries there were important factors which the economies of the muslim empires developed increasingly. they applied economic procedures in production, investment, finance, taxation and property. they used to tax certain goods (for example: harvest), they charged interest on money lent, they signed contracts with merchants; they relied on a common currency, and they used checks as well as promissory notes. with the money collected by means of taxation, the government provided the needy with an income. in addition, trading networks covered huge distances, so far regions started to have contact and exchange goods. this trade network covered areas of asia, africa and europe.
