Mr. Tyler wants to have roses delivered to a banquet. Flowers to Go charges $2.50 per rose and $9 for delivery. Blooms R Us charges $3.25 per rose and $5 for delivery. What is the minimum number of roses Mr. Tyler needs to purchase in order for Flowers to Go to have a lower price than Blooms R Us?

Step-by-step explanation:

Step one:

Given data

Flowers to Go charges

let the number of roses be x

and the total cost be y

$2.5 for a rose

$9 for delivery

the total cost is

y=2.5x+91

Blooms R Us charges

let the number of roses be x

and the total cost be y

$3.25 for a rose

$5 for delivery

the total cost is

y=3.25x+52

Step two:

equating equations 1 and 2 we can solve for x, the number of flowers

2.5x+9=3.25x+5

2.5x-3.25x=5-9

-0.75x=-4

x=4/0.75

x=5.33

Therefore the minimum number of flowers is 5.33

40% off the regular price is the correct answer.
