There are 870 boys and 800 girls in a school
alina1380 [7]

Answer:

1060

Step-by-step explanation:

Given:

No. of boys = 870

No. of girls = 800

Probability that a boy chosen studies Spanish = \dfrac{2}{3}

Probability that a girl chosen studies Spanish = \dfrac{3}{5}

the number of boys in the school who study Spanish :

\dfrac{2}{3}\times 870=290\times 2=580

the number of girls in the school who study Spanish :

\dfrac{3}{5}\times 800 \\=3\times 160\\\\=480

Therefore, total number of students who study Spanish would be :

480+580=1060

A compact disc player costs £50 plus 17 1/2% Vat. Calculate the total cost of the compact disc player
Shtirlitz [24]
With Calculator:
To work out the multiplier, take the percentage, divide by 100 and add 1
17.5% / 100 = 0.175
1 + 0.175 = 1.175
£50 x 1.175 = £58.75

Without Calculator:
First work out easy percentages of 50 (if needed use previous answers (such as 10) to work out smaller percentages (such as 5%))
100% = 50
10% = 5
5% = 2.5
2.5% = 1.25
10% + 5% + 2.5% = 17.5%
5 + 2.5 + 1.25 = £8.75
Add this on to the original price:
£50 + £8.75 = £58.75

The total price, including VAT, is £58.75
