5% of £42 = £2.10
10% of £42 = £4.20
15% of £42 = £6.30
£42 - £6.30 = £35.70
£50 - £35.70 = £14.30
the answer is £14.30
Percent Change = New Value − Old Value|Old Value| × 100%
Example: There were 200 customers yesterday, and 240 today:
240 − 200|200|× 100% = 40200 × 100% = 20%
A 20% increase.
Percent Error = |Approximate Value − Exact Value||Exact Value| × 100%
Example: I thought 70 people would turn up to the concert, but in fact 80 did!
|70 − 80||80| × 100% = 1080 × 100% = 12.5%
I was in error by 12.5%
(Without using the absolute value, the error is −12.5%, meaning I under-estimated the value)
The difference between the two is that one states factual calculations and the other is a theoretical guess
Answer:
Step-by-step explanation:
To determine how much wax you will need, you will first need to decide on ... (ounces needed) ÷ 16 (ounces in 1 pound) = (pounds of wax needed). For example, let's say you wanted to make 25 candles in our 8 oz Candle Tins ... 5 x 25 = 125 oz of wax ... It's always better to have a little wax left over than to not have enough!
