How long does it take $500 to double at a simple interest rate of 24%?
yuradex [85]

Answer:

4 years and 2 months

Step-by-step explanation:

<u>Simple interest formula</u>

A = P(1 + rt)

where:

  • A = final amount
  • P = principal amount
  • r = interest rate (in decimal form)
  • t = time (in years)

Given:

  • A = $500 × 2 = $1,000
  • P = $500
  • r = 24% = 0.24

Substitute the given values into the formula and solve for t:

\implies \sf 1000 = 500(1 + 0.24t)

\implies \sf \dfrac{1000}{500}=(1 + 0.24t)

\implies \sf 2=1 + 0.24t

\implies \sf 1 = 0.24t

\implies \sf t=\dfrac{1}{0.24}

\implies \sf t=4 \frac{1}{6} \:years

\implies \sf t=4\:years\:2\:months

Therefore, it takes 4 years and 2 months for the initial investment of $500 to double at a simple interested rate of 24%.

Solve system with substitution
SpyIntel [72]

Answer:

The cost of 1 Rose Bush= $ 8

The cost of 1 Shrub =  $12.

Step-by-step explanation:

The cost of 11 rose bushes and 4 shrubs =  $136

The cost of 2 rose bushes and 11 shrubs =  $148

Let the cost of one rose bush =  $x

and the cost of one shrub  =  $ y

Now, according to the question:

11 x + 4 y = 136

and 2 x + 11 y  = 148

From (1), we get that 11x  = 136 - 4y

or, x = \frac{136 - 4y}{11}

Substitute this value of x in equation (2), we get

2 x + 11 y  = 148  \implies 2( \frac{136 - 4y}{11})  + 11y  = 148

or, ( \frac{272 - 8y}{11})  + 11y  = 148  \implies 272 - 8y + 121y = 1628

or, 113 y = 1356

or, y = 1356/113 = 12

⇒ y = 12, So x  =  \frac{136 - 4y}{11}  = \frac{136 -12(4)}{11} = \frac{136 - 48}{11}  = 8

or, x  =8 and  y = 12 is the solution of the above system.

Hence, the cost of 1 rose bush  = $x = $8

and  The cost of 1 shrub = $ y = $12.
