PLEASEE HELP ASAP!!!!!

A new drug being developed by a company is said to be 70% effective at wiping out bacteria. After using the drug, if there are over 100,000 bacteria left the patient is said to still be infected. The new drug will be 40% more expensive to produce than what is currently available.


A. A new patient has 421,000 bacteria in their blood and starts the new drug. How many will be left after taking the new drug?


B. The original drug costs $31.50. How much will the new cost?


C. If the company produces them with a $11 profit, how much does the drug cost to make? How many drugs does the company need to produce to make a $2 million profit?

For A, you take 70% of 421,000 and subtract that from 421,000. You should solve like this: 421,000 - (0.7 x 421,000).

For B, you take 40% of 31.50 and add it to 31.50. (31.50 + (31.50 x 0.4).

This is all I can give for now. Glad to help you!

Answer:

A) Bacteria left after taking the new drug = 126,300 bacteria

B) The new cost is $44.10

C) the has to produce 181,819 drug to make $2 million profit.

Explanation:

Given:

New drug eliminate 70% of bacteria. If there are over 100,000 bacteria after the new drug the patient has to take another drug which cost 40% more expense.

Part A

A new patient has 421,000 bacteria.

The new drug eliminate 70% of the bacteria.

Eliminated bacteria = 70% of 421,000

=
(70)/(100) *421,000\\=0.7*421,000\\= 294,700

Bacteria left after taking the new drug = 421,000 - 294,700

Bacteria left after taking the new drug = 126,300 bacteria

Part B

The new cost 40% more than $31.50

New cost = $31.50 + 40% of 31.50

=
= 31.50 + 0.4*31.50\\= 31.50 + 21.60\\= $44.10

The new cost is $44.10

Part C

The company produces them with $11 profit.

The company has to make $2,000,000 profit.

The number of drug produce = $2,000,000 divided by $11

=
(2000000)/(11) = 181,818.18

The drug cannot be in decimal form.

So, the company has to produce 181,819 drug to make $2 million profit.
