Question

You want to buy a bouquet of yellow roses and baby's breath for $16. The baby's breath cost $3.50 and roses cost $2.50 each. You want one baby's breath and some roses for your bouquet.

Find the number of roses that you can buy.
Write equation and solve for (r)

Answer 1

Equation: 16 = 2.50r +3.50

Answer: r = 5

Explanation:

since we know that we want only one Baby Breath we can add 3.50 to the end of our equation. So all we need to do is solve for the number of roses (r)

16 = 2.50r +3.50

16 - 3.50 = 2.50r

12.50 = 2.50r

with that we divide both sides by 2.50 and get

5 = r
