Elvira can purchase ready-made pizzas for $14.50 each. if she makes them in the cafeteria, she can spend $44.20 on ingredients and $6.25 per pizza on labor. for how many pizzas is it cheaper for the cafeteria to make the pizzas themselves rather than buy them ready-made?

The total cost if the cafeteria makes the pizza is:

cost = 44.20 + 6.25 p

where p is the number of pizza

while the cost if it is ready made is:

cost (ready made) = 14.50 p

Equating the two to find for x:

44.20 + 6.25 p  < 14.50 p

p > 5.35

So it is cheaper when 6 pizzas or more is made

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
