Question

Erika's toy is valued at €450. Its value increased by 10% then decreases by 10% the year after. What is the value of Erika's toy after these two changes?

Answer 1

• €445.50

-------------------------

Initial value of the toy is €450.

After 10% increase the value is:

• €450 + 10% =
• €450*1.1 =
• €495

After further 10% decrease the value becomes:

• €495 - 10% =
• €495*0.9 =
• €445.50

The final value of the toy is €445.50.
