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?

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

yes

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
