2) What is the value of n? - n = 3
3) How many boxes does she need to buy? - I can't remember which way round it was, but she needed 8 of one and 12 of another.
4) Can he ship the microwaves? - Yes, he has room for 600.
5a) How much (flour i think) does she need for 12 servings? - 15 ounces

7a) a^4 * a^3? - a^7

8a) 0.00059 in surd from? - 5.9^4
b) 3.7^5? - 370000, i'm not sure about the numbers in this one but the answer had than number of zeros!9) Draw this graph. - You should have had a straight line from -2,-6 to 3,7
11) What is the formula of the line through m, perpendicular to the other line? - y = -1/2 x + 8.5

From here i can't remember a few so these question numbers are a guess.

a* - 55
a - 50

d - 14
e - 8
