(2)
Theo spent the remaining £10 on bus fares and food.
He spent £1.50 more on bus fares than on food.
(c) How much did he spend on bus fares?

Answer 1

is a.1/5
b.30% and c..i dunno

Answer 2

b for bus and f for food. we can say
b+f =10

£1.50 more on bus fares than on food. means that b = 1.50 more than food or
b= 1.50 + f

replace b with 1.5 + f in the first equation:
1.5 + f + f =10

now solve for f. can you do that ?

Answer 3

then use b+f =10 to solve for b: b= 10-f

or we could do it this way:
b= 1.5+f so f= b - 1.5
replace f with b-1.5 in b+f=10

b + b - 1.50 =10

now solve for b
