Someone, please help me

Mathematics
1 answer:
dimulka [17.4K]3 years ago
6 0

Answer:

4.3%

Step-by-step explanation:

Write out the formula for simple interest:

i = p r t, where i is the interest earned, p is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.

Here, this i = p r t becomes

$645 = $3000*r*(5 yr).

This is equivalent to:

$645 = $15000r.

Solving for r by dividing both sides of this equation by $15000, we get

     $645

r = ------------ = 0.043

     $15000

Thus, the correct answer is the first one:  4.3%

mary purchased 3 1/2 pounds of bananas. If the loaf of banana bread requires 3/4 pounds of bananas, how many loaves of banana br
nikklg [1K]
For this one a simple way that you can think of it is that 1 pound of banana is equivalent to 100, 3/4 pounds of banana is 75, 1/2 pounds of banana is 50, etc. 

3 1/2 pounds of banana = 350 

3/4 pounds of banana = 75 

If i want to find out how many loafs of banana bread I can make if ONE loaf requires 3/4 pounds of banana, and i have 3 1/2 pounds of banana then I divide:

350 / 75 = 4.66 

So, with 3 1/2 pounds of bananas you can successfully create 4 loafs of banana bread. the remaining .66 is not enough banana to make another loaf.
