Answer:
As per the statement:
Mr. Roseanne will buy [tex]12\frac{1}{2}[/tex] pounds beef for for a cookout.
⇒ Weight of the beef he buy = [tex]\frac{25}{2}[/tex] pounds.
It is given that:
The price for the first 3 pounds of beef is $4.99 per pound.
then;
the price for 3 pounds he will pay= [tex]3 \times 4.99 =\$ 14.97[/tex]
After that, the price is $4.49 per pound.
Remaining weight of beef left = [tex]\frac{25}{2} -3 = \frac{19}{2}[/tex] pounds.
then;
the price of [tex]\frac{19}{2}[/tex] pounds he will pay = [tex]\frac{19}{2} \times 4.49= \$42.655[/tex]
now, total money he will pay for the [tex]12\frac{1}{2}[/tex] pounds beef = [tex]14.97+42.655 = \$57.625[/tex]
Therefore, $57.625 will Mr. Roseanne pay for the beef
