Item 10 Find the amount of time. I=$450, P=$2400, r=7.5%

Alex787 [66]

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 ;

 P = $2400 ;

r = 7.5% = 7.5/100 = 0.075 ;

Plug in these values into the formula to solve for the time, "t" :

 → t = I / (P * r ) ;

= $450 / ($2400 * 0.075) ;

= $450 / ($2400 * 0.075) ;

= $450 / $180 ;

= $45 / $18 ;

= ($45 ÷ 9) / ($18 ÷ 9)

= $5 / $2 ;

= 2.5 ;

→ t = 2.5 years.

Murljashka [212]

Answer:

18/44

Step-by-step explanation:

To turn 9/22 into something over 44, we need to figure out what to multiply it by.

44 / 22 = 2.

Multiply 9/22 by 2:

9/22 * 2 = 18/44
