A 1-liter bottle of orange juice used to cost $2.85 at a food market. Its price has increased; the new price is 110 percent of t
AfilCa [17]

Answer:

The new price of the bottle is $ 3.14.

Step-by-step explanation:

Given,

Original price of 1-liter bottle of orange juice  = $ 2.85,

Since,  the new price is 110 percent of the original price.

Thus, the new price of the bottle = 110 % of the $ 2.85

=\frac{110\times 2.85}{100}

=\frac{313.5}{100}

=3.135\approx 3.14

Hence, the new price of the bottle is $ 3.14.
