ioda2 years ago
8 0

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?

Answer:

y=2500(0.85)^d

Step-by-step explanation:

Seeing as there are no option choices, I shall digress.

Because of a decrease of 15% each day, it means exponential decay. Using the formula y=a(1-r)^x, we have y=2500(1-0.15)^d -> y=2500(0.85)^d

Your function would thus be y=2500(0.85)^d
