Workers in an office of 90 staff were asked their favourite type of take-away. The results are summarised in the table. Take-away Frequency Angle Pizza 20 a Curry 24 b Fish & chips 10 с Kebab 15 d Other 21 e What fraction of a person is one degree? Give your answer in its simplest form.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
