Help I don’t understand this

y = 12.5

Step-by-step explanation:

Notice these are similar triangles since they have angles of the same measure (congruent angles), then there must be a proportion among their sides such that:

therefore by cross-multiplying, we get:

4(y + 5) = 14 * 5

4 y + 20  = 70

4 y = 70 - 20

4 y = 50

y = 12.5

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.
