Simple Interest Rate Formula: $\displaystyle A = P(1 + rt)$

P is principle amount
r is rate
t is time

Step-by-step explanation:

Step 1: Define

Identify variables

P = 100

r = 4% = 0.04

t = 10

Step 2: Find Interest

Substitute in variables [Simple Interest Rate Formula]: A = 100(1 + 0.04 · 10)
(Parenthesis) Multiply: A = 100(1 + 0.4)
(Parenthesis) Add: A = 100(1.4)
Multiply: A = 140

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each sale

Katarina [22]

Answer:

12 sales

Step-by-step explanation:

Let x represent the number of sales each man had.

For Salesman A, he earns $65 per sale; this is 65x.

For Salesman B, he earns $40 per sale; this is 40x. We also add to this his weekly salary of $300; this gives us 40x+300.

Since their pay was equal, set the two expressions equal:

65x = 40x+300

Subtract 40x from each side:

65x-40x = 40x+300-40x

25x = 300

Divide both sides by 25:

25x/25 = 300/25

x = 12

A scientist counts 25 bacteria present in a culture and finds that the number of bacteria triples each hour. The function y = 25

Anvisha [2.4K]

$y = 25\cdot~3^x\\ \\ 1170 = 25\cdot~3^x\\ \\ \frac{1170}{25} = 3^x\\ \\ \frac{243}{5} = 3^x\\ \\ log\ \frac{243}{5} = log~3^x\\ \\ log~243-log~5=x~log~3\\ \\ 
 log~3^5-log~5=x~log~3\\ \\ 5~log~3-log~5 = x~log~3\\ \\ 5(0,48)-0,70= 0,48x\\ \\ 2,4-0,7 = 0,48x\\ \\ 1,7=0,48x\\ \\ x=\frac{1,7}{0,48}\\ \\ \large{\boxed{x=3,54\ h}}$
