Lakisha needs 84 pounds of ground beef for a party. She can buy
ground beef in 1-pound, 22-pound, or
3-pound packages. If Lakisha wants to
spend the least amount of money, which
packages should she buy and how many?
CROUND BEES
1 lb. for $3.20
GROUND BEEF
3 lb. for $9.50
GROUND BEEF
2 lb. for $7.50

the 3 lb pack of ground beef is the cheapest; she will need to buy 28 packs.

Step-by-step explanation:

1 lb = 3.20

3 lbs = 9.50 = 1 lb = 3.17

2 lbs = 7.50 = 1 lb = 3.75

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

what are ur choices?
