Let the additional fee , the shipping company charges be $y .
So for 0.75 pounds, since the weight is less then 1 pound, company charge = $2x
For 3 packages with weigh 2.5 pounds, company charge 3* ( x+(2.5-1)*y )
= 3x+4.5y
For package with weighs 4.2 pounds, company charge x+(4.2-1)y = x+3.1y
So the total amount , company charge = 2x +3x +4.5y +x+3.1y
=6x +7.6y
Answer:
Greatest number of flowers in a bouquet = 9 flowers
Step-by-step explanation:
Total no. of roses = 18
Total no. of daisies = 9
Total no. of tulips = 45
To find the greatest no. of flowers that can be arranged in the bouquet such that there are same number of flowers and same type of flowers in the bouquet, we will take the H.CF (highest common factor) of 18,9,45
H.C.F of 18,9,45 = 9
Hence, the greatest number no. of flowers that can be arranged in the bouquet = 9 flowers.
2.8-(-5.1)
-(-5.1)=5.1
2.8+5.1= 7.9
