A restaurant sells sandwiches for d dollars. To keep up with rising costs the owner will increase the price of each sandwich by 10%. Write an expression to represent the new cost of a sandwich?

Answer: d+0.1d

Step-by-step explanation:

The price of sandwich in the restaurant is d dollars.

Due to increase in cost, there was a price increased and 10% was added to the earlier price.

To get the new price, we add the earlier price to 10% of the earlier price.

Earlier price = d

New price = d + (10% of d)

= d + (10/100 * d)

= d + 0.1d
