roses cost $38.70. In dollars and cents,
what is the cost of a single rose?

Answer 1

Using proportions, it is found that the cost of a single rose is of 3.225 dollars = 322.5 cents.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, 12 roses cost $38.70, hence the price of a single rose is given by:

p = $38.70/12 = $3.225.

Considering one dollar has 100 cents, the price in cents is given by:

C = 3.225 x 100 = 322.5.
