Erika set up a cupcake stand at a local flea market this past weekend. Each cupcake sold for $3. On Saturday, she sold 150 cupcakeson Sunday, she sold 100 cupcakes. If Erika's expenses were $300, what were her profits?

$450

Step-by-step explanation:

150 x 3=450

100 x 3=300

450+300=750

750-300=450

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
