Answer:

$80

Step-by-step explanation:

The final price of $42 was after a 25% off coupon was applied.

Therefore, $42 is 75% of the price before the coupon was applied.

So cost before coupon applied = 42/75 x 100 = $56

The price of $56 was after the 30% mark down was applied.

Therefore, $56 is 70% of the price before it was marked down.

So cost before mark down applied = 56/70 x 100 = $80
