ioda

Answer:

£2.00

Step-by-step explanation:

Badly worded, as they oftena are! But to me it means

30% spent

60% saved (I.e also taken away and put somewhere else)

10% leftover equals 20p

So 20p equals 10% of what she originally had, so 100% must be £2.00, does that make sense?

Step-by-step explanation:

perimeter of a rectangle = 2( width + length )

P = 2 ( x - 2 + x + 7 )

P = 2 ( x + x + 7 - 2 )

P = 2 ( 2x + 5 )

P = 4x + 10
