Initially Kevin had 25

Step-by-step explanation:

Given that,

James have 20 more than Kevin

J = K + 20

If Kevin loose 10 then james will have 3 time Kevin

J = 3( K - 10)

Equate both the equation,

3(K-10) = K+20

3k - 30 = k +20

3k - k = 20 + 30

2k = 50

K = 25

So initially Kevin had 25

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.
