(1) Welsona has some money. She spent $17.40 on 3 notebooks and 8 highlighters. He is short of 80cents if he were to buy another notebook. However, if he were to buy another highlighter, he will have 60cents left.

(a) Find the cost of a notebook.

(b) How much money does Welson have?

(2) Xania and Criven cycle from Town A to Town B which is 87.5km apart. Xania cycles at a speed of 27 km/h and Criven cycles at a speed of 35 km/h.

(a) If Xania starts cycling 40 minutes earlier than Criven, how long will Criven take to catch up with her.

(b) How far away is Xania from Town B when Criven arrives at Town B

(3) During an interclass game, each group of pupils had to collect as many colored balls as possible from a box. Each colour represents a certain number of points as shown below.

Yellow 4

green 3

red 5

The number of yellow balls in the box was 20% more than the number of red balls and 10% less than the number of green balls. If a group of pupils managed to collect all the balls and the total possible points was 1035, how many yellow and red balls were there in the box altogether.

11u--> 13.20

1u--> !.20

Notebook--> 1.20+1.40=2.60

Amount he has --> 17.40 + (2.60- 0.8) = $19.20

(3) R : Y : G

100 120

90 100

30 : 36 : 40

30u(5) + 36u(4) + 40u(3) = 1035

U=2.5

Y+ R --> 66u --> 165
