Work out the percentage change to 2 decimal places when a price of £57.99 is decreased to £49.99.

IRISSAK [1]

Answer:

Percentage change in price = 13.80%

Step-by-step explanation:

Given that:

Original price = £57.99

Decreased price = £49.99

Difference = Original price - Decreased price

Difference = 57.99 - 49.99

Difference = £8.00

Percent change = $\frac{Difference}{Original\ price}100$

Percent change = $\frac{8.00}{57.99}*100$

Percent change in price = 13.80%

Hence,

Percentage change = 13.80%

Mekhanik [1.2K]

Answer:

B & C

Step-by-step explanation:

Use the Pythagorean Theorem: a^2 + b^2 = c^2

A) 18^2 + 24^2 = 2,088 | 42^2 = 1,764 [NOT A]

B) 33^2 +56^2 = 4,225 | 65^2 = 4,225 [B IS CORRECT]

C) 19^2 + 180^2 = (32,761) = 181^2 = (32,761) [C IS CORRECT]

D) 3^2 + 4^2 = 25 | 7^2 = 49 [NOT D]

I hope this helped you ! In return, please deem this the most brainliest answer.
