You bought an investment for $1000 and 5 years later sold that investment for $1700. taking into account compounding, what was your average annual return during the investment? round your answer to the nearest tenth of a percent and use decimals

11.19%

Step-by-step explanation:

We will use compound interest formula :

A = accumulated value = $1,700

P = principal amount   = $1,00

r  = rate of interest = ?

n  = number of compounding = 1

t   = time = 5 years

Now put the values into formula

1.7 = (1+r)⁵

1.1119 = 1 + r

r = 1.1119 - 1

r = 0.1119

R = 0.1119 × 100

  = 11.19%

Average annual return was 11.19%

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
