Answer:
Y=3x+5
Step-by-step explanation:
If we take x = 1, according to the first function (the answer) y would be 8.
Other options:
—————
Formula 3:
Y= 2^x+5 == 7
Formula 4:
Y = x+8 == 9
True answer = 10.
——————
Ok, so the last one seems more accurate lets test the first and last one on two more numbers:
——————
X = 15
Formula 1:
50
Formula 4:
23
True answer = 60.
The first formula wins.
————————-
X= 10
Formula 1:
35
Formula 4:
18
True answer = 41
The first formula wins.
——————
So, we can see that the first formula is most accurate.

The answer is: "2.5 years" .

Note: I = P * r * t ; { " Interest = Principal * rate * time "} ;
→ Solve for "t" {"time", in years} ;
Divide each side of the equation by "{P * r}" ;
to isolate "t" on one side of the equation ;
→ I / (P * r) = {P * r * t) / (P * r} ;
to get: " I / (P * r) = t " ;
↔ t = I / (P * r) ;
Given: I = $450 ;
<span>P = $2400 ;
r = 7.5% = 7.5/100 = 0.075 ;
Plug in these values into the formula to solve for the time, "t" :
</span>→ t = I / (P * r ) ;
= $450 / (<span>$2400 * 0.075) ;
= </span>$450 / ($2400 * 0.075) ;
= $450 / $180 ;
= $45 / $18 ;
= ($45 ÷ 9) / ($18 ÷ 9)
= $5 / $2 ;
= 2.5 ;
→ t = 2.5 years.
