(i) Challenge: Thembi received 8% discount on an item which cost
Paul [167]

Answer:

x = 0.25

Step-by-step explanation:

Given

Cost\ Price = 6 + x

Discount =8\%

Amount\ Paid = R6 - x

Required

Find x

First, we calculate the amount paid in terms of the cost price.

This is calculated using:

Amount\ Paid = Cost\ Price * (100\% - Discount)

Amount\ Paid = (6 + x) * (100\% - 8\%)

Amount\ Paid = (6 + x) * 92\%

Express as decimal

Amount\ Paid = (6 + x) * 0.92

Open bracket

Amount\ Paid = 5.52 + 0.92x

So, we have:

Amount\ Paid = 5.52 + 0.92x and

Amount\ Paid = R6 - x ---- given

Equate both

6 - x = 5.52 + 0.92x

Collect like terms

- x -0.92x= 5.52-6

-1.92x= -0.48

1.92x= 0.48

Solve for x

x = \frac{0.48}{1.92}

x = 0.25

1. Jeremy has $12000 cash to invest in the bank compounded at 4% interest annually.
gavmur [86]

Answer:

A(x) = 12000(1.04)^x

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$12000 cash

This means that P = 12000

Compounded at 4% interest annually.

This means that r = 0.04, n = 1

What equation will calculate the value in x years?

A(t) = P(1 + \frac{r}{n})^{nt}

A(x) = P(1 + \frac{r}{n})^{nx}

A(x) = 12000(1 + 0.04)^x

A(x) = 12000(1.04)^x
