Question 8:

Your answer of

Answer 'A' - $70

is correct.

Bravo

There was actually a quick way to the answer. Did you spot it?

In the final purchase, the stationery, Jennifer spent half of the remainder + $5 and then had nothing left, so $5 was half the cost of the stationery. Get it?

Therefore : (X ÷ 8) - 3.3/4 = 5

.......................................X - 30 = 40..................... Multiply throughout by 8

..................................... .........X = 70
