You start by changing the fraction into a decimal.
4.5 lb. of ground beef= 16.11
6.25 lb. of ground turkey= 18.50
Next, you divide the amount they cost by the pounds to get the price per pound.
16.11÷4.5= 3.58
18.50÷6.25= 2.96
So, a pound of beef is $3.58, and a pound of turkey is $2.96.
The turkey is 62 cents less than the beef per pound.
That means the turkey is a better buy! :)

Answer:
x = 7 / 2
Step-by-step explanation:
5(2x - 9) + 3 = -7 ---------- subtract 3 from both sides
5(2x - 9) + 3 - 3 = -7 - 3
5(2x - 9) = -10 ------ divide both side by 5
2x - 9 = -2 ---------- add 9 to both sides
2x - 9 + 9 = -2 + 9
2x = 7
x = 7 / 2
Translation by h right and k up: f(x-h)+k.
Vertically scale by k and reflect across the x-axis: -k·f(x).
After the translation, your function is
f(x) = (x-2.5)² -7
After the scaling and reflection, your function is
f(x) = (-2/5)((x -2.5)² -7)
