Sean pays £10 for 24 chocolate bars. He sells all 24 chocolate bars for 50p each.

VladimirAG [237]

Answer:

the percentage profit is 20%

Step-by-step explanation:

Given that

Sean paid £10 for 24 chocolate bars

He sold all 24 chocolate bars for 50p each

we need to find out the percentage profit

Since he paid £10 and sale value is (24 × 0.50) i.e. £12

So, the percentage profit is

= (£12 - £10) ÷ (£10)

= 20%

Hence, the percentage profit is 20%

Natalie earned $200 in interest and 30 months with a beginning balance of $1040. What was her interest rate?

rjkz [21]

The interest rate is 7.69%

Step-by-step explanation:

Given

Interest = $200

Time = t = 30 months

Time will be converted into years as the rate is applied yearly

So,

1 year = 12 months

30 months = 30/12 years = 2.5 years

Principal amount = $1040

The formula for interest is:

$I = P*r*t$

Putting the values

$200 = 1040 * r * 2.5\\200 = 2600r\\r = \frac{200}{2600}\\r = 0.076923$

Converting into percentage:

r = 7.6923

Rounding off to nearest hundredth

r = 7.69%

Hence,

The interest rate is 7.69%
