Paul has £7.80 pocket money each week.
He always saves 1/3 of it.
With the remaining money he spends on
comics and the rest on sweets.
(i) How much does he save?
(ii) How much is spent on comics?
(iii) How much does he spend on sweets?

i) $2.60 is money he saves each week

ii( iii)  $5.20 to spend on comics and sweets.

You need more info to determine how he spends his money thereafter.

Lets say x = sweets and y = comics.

and lets say he spends under 1/3 on sweets

2(1 1/5x + 1 1/2y) = xy

2 2/5x + 3y = xy

xy = 5 2/5

Step-by-step explanation:

i) 7.80 /3 = 2.60  = $2.60

ii) 7.80-2.6 = 5.20 = $5.20

iii) algebra example or refer to question for more info not shown.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

i got 86 for this

hope this !

if you need an explanation just ask
