Answer:
$67.50
Step-by-step explanation:
Multiplying $100 by 0.75 results in $75. This price reflects the 25% off discount.
Multiplying this $75 by 0.90 results in $67.50. This price reflects both the initial 25% discount and the additional 10% discount.
The number that should be added on both is 7.
