Abus ticket into town costs £1.20 for an adult and 80p for a child. if the prices are raised by 7% how much will it cost for 1 adult and 1 child to go to town on a bus?

You have to find 7% of each of the prices and then add that onto the original price...
adult increase... 1% of £1.20 = £0.12 x 7 (to find 7%) = £0.84
child increase... 1% of 80p = 0.8p x 7 (to find 7%) = 5.6p (rounded... 6p)

adult new price... £1.20 + £0.84 = £2.04
child new price... 80p +6p = 86p

adult and child added new price... £2.04 + £0.86 = £2.90
Hope this helps :)

£2.90 is the total price for one adult and one child getting a bus ticket.

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
