Over the centuries, Caveman Colin has carved these original
questions into his stone tablets in a forgotten corner of Dorset,
hoping that someone would come along and try to do them.

1. Jimmy earns £5 per week doing a paperround in 1998.
If he gets a 10% payrise in 1999, how much does he earn per week, and how much altogether in 1999?
For 2000, he has fewer papers to deliver, so he gets a 10% pay cut; what is his new weekly pay?

2. A family spends £400 each year on a holiday. £50 of this is travelling costs, £80 is
spending money and the rest is accommodation. If the accommodation costs rise by 10% next year
what will their holiday cost altogether?

3. Samantha has a parttime job which pays £24 per week. If she saves 25% in the Building Society
and spends £1.20 a week on drinks after sports, what does she have left for shopping?
What percentage of her total pay is this?

4. Two brothers, Joe and Jack, have parttime jobs. Joe earns £18 every Saturday, Jack has a paper
round, MondayFriday in termtime only (36 weeks per year) and earns £5 per day. Who earns most in
one year?

5. Suppose a man has to earn more than £1600 per year before having to pay income tax.
Calculate his maximum weekly pay if he doesn't pay any tax.

6. I set off from San Diego at 18.30 San Diego time. The 13hour flight finished at
Heathrow at what time (San Diego time)? If UK time is 8 hours later than San Diego time,
what time did I land at Heathrow? My journey to Dorset took 3 hours, what time did I
get home?

7. Which is colder, 5.5 degrees less than 2.5 degrees, or 7 degrees less than 3.2 degrees?

8. Frozen fish must be kept below 25 degrees C. frozen fruit below 15 degrees C.
Jenny's freezer is at 22 degrees C, Fred's is at 11 degrees C.
Which probably lasts longer, Fred's fruit or Jenny's fish?

9. Simplify these where possible:
(i) 5p+3q+2p+p4q
(ii) x+y5z+2y+y8z+2x
(iii) r+3sr6rs
(iv) 5q3r+16s
(v) ab+6ba3a+14ba
(vi) pq+3rs+sr+20qpr^{2}
(vii) x+x^{2}6+4x+3+4x^{2}
(viii) i^{2}+2ji+j^{2}ijij+jii^{2}

10. expand then simplify the expression: (x+2)(x2).
