Answer:
Step-by-step explanation:
You have the following polynomial:
This expression is of the form:
that is, a difference between cubes. The factorization of such a polynomial is given by:
You apply the last expression to the polynomial given in the problem. But first you have:
finally, you obtain:
I = PRT
Replace the letters with the given numbers:
350 = 700 * 0.10 * T
Simplify:
350 = 70 * T
Divide both sides by 70 to find T:
T = 350 / 70
T = 5 years

Answer:
6.95
Step-by-step explanation:
to find how much stephanie spends for first we will find how much probhjot spends and then subtract 3.45 dollars from that value alvin spends 2.60 dollars
prohbjot spends 4 times as much as alvin or
4× 2.60=10.4
so prohbjot spends 10.4 dollars
stephanie spends3.45 dollars less than prohbjot or
10.4 -3.45 =6.95
so stephanie spends <u>6.95 </u>dollars
