Answer:

C

Step-by-step explanation:

when we factored the expression 15c2 + c – 28

= 15c2 + 21c-20c – 28

=3c(5c+7c)-4(5c+7c)

=(3c-4)(5c+7c)

hence the given expression is not equivalent, but it is completely factored.

If a man earns $420 interest in one year at 7%, what was the amount of money invested?
ivanzaharov [21]
We know, interest value = P * R * T /100
Here, I = 420
R = 7%
T = 1 

Substitute their values, 
420 = P * 7 * 1 /100
P = 420*100 / 7
P = 60*100
P = 6000

In short, Your Answer would be Option D) $6,000

Hope this helps!
