(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.
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.
Amount he has --> 17.40 + (2.60- 0.8) = $19.20
(3) R : Y : G
30 : 36 : 40
30u(5) + 36u(4) + 40u(3) = 1035
Y+ R --> 66u --> 165
