At a grocery store, blueberries come packaged in 8-ounce containers for $2.80. at a farmer's market, blueberries cost $4.20 for 14 ounces. there are 16 ounces in one pound. which statement accurately compares the cost of blueberries?

blueberries are $0.23 per pound more expensive at the farmer’s market.
blueberries are $0.50 per pound less expensive at the farmer’s market.
blueberries are $0.80 per pound less expensive at the farmer’s market.
blueberries are $1.40 per pound more expensive at the farmer’s market.

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.

the answer is ! ?
