Answer:
The original price of the phone is £388.
Step-by-step explanation:
Since 5% of the price of the phone is reduced, you can simply multiply the reduced number which is £19.4 by 20. Your final answer should be £388 when you put it on a calculator or do it on a piece of paper.
Step-by-step explanation:
8.3 = 8+ 0.3
= 8 + 3/10
= 8 3/10
Answer:
4/9, or 0.4∞

32*1.2=38.4 (.2 is the 20%, and the 1 adds the percent to the original cost making it a mark up)
The z-score of Kimmie is -0.625
<h3>Calculating z-score</h3>
The formula for calculating the z-score is expressed as;
z = x-η/s
where
η is the mean
s is the standard deviation
x is the Kimmie score
Substitute the given parameter
z = 85.9-88.4/4.0
z = -2.5/4.0
z = -0.625
Hence the z-score of Kimmie is -0.625
