D. Lucia purchases stock in Pherk, a pharmaceutical company.

Answer and explanation:

Saving implies setting an amount of money of your income aside and put it into a bank account or store it somewhere considered safe. If deposited in a bank the money gains interest, thus, there will be a relative increase in the initial sum deposited.

Investing implies providing money to a third party or using that money personally to start up a venture. In such cases, there is a risk that the investment could be lost.

Thus:

A) Ginny buys new bulldozers for her construction firm.  (Investment)

B) Eric purchases a certificate of deposit at his bank.  (Saving)

C) Kenji takes out a mortgage for a new home in Detroit. (Investment)

D) Lucia purchases stock in Pherk, a pharmaceutical company. (Saving)

x=3

step-by-step explanation:

this is really simple i saw that there was only one term (5x) and thought if that was 15 what would i have to multiply everything else to get it there? well if 5x became 15 then x would have to be 3 so plug the 3 in the x for the other equations and you get 15 for the other ones. so there you go. : )
