Whoever can solve all these is the best. y = 5x + 9m =
y = -3x + 4m =
y = 6 – 7xm =
y = 15 – 12xm =

hope these helps

Step-by-step explanation:

y = 5x + 9m = 5

y = -3x + 4m = -3

y = 6 – 7xm = -7

y = 15 – 12xm = -12

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
