Daisy's Flowers sell a rose bouquet for $39.95 plus $2.95 for every rose. A competing florist sells a similar bouquet for $26.00 plus $4.50 for every rose. Find the number of roses that would make both florists' bouquets cost the same price.

Step-by-step explanation:

Step one:

given data

For Daisy's Flowers

the cost is $39.95

an additional $2.95 for every rose

let the number of rose be x

the linear model for the cost is

y=39.95+2.95x1

Step two

For  the competing florist  

the cost is $26

an additional $4.5 for every rose

let the number of rose be x

the linear model for the cost is

y=26+4.5x2

Step three:

equating the two above equations to find the number of roses x

we have

39.95+2.95x=26+4.5x

solve for x

39.95-26=4.5x-2.95x

13.95=1.55x

divide both sides by 1.55

x=13.95/1.55

x=9

Hence the number of roses that would make both florists' bouquets cost the same price is 9 roses

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
