Answer:
As per the statement:
Mr. Roseanne will buy
pounds beef for for a cookout.
⇒ Weight of the beef he buy =
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=
![3 * 4.99 =\$ 14.97](https://img.qammunity.org/2020/formulas/mathematics/high-school/bdbqu5si54qicsa53av9canyz9a3vag7zu.png)
After that, the price is $4.49 per pound.
Remaining weight of beef left =
pounds.
then;
the price of
pounds he will pay =
![(19)/(2) * 4.49= \$42.655](https://img.qammunity.org/2020/formulas/mathematics/high-school/nfunc5m8ixmeqpy3w6s1wr3v9t5ui9dh9f.png)
now, total money he will pay for the
pounds beef =
![14.97+42.655 = \$57.625](https://img.qammunity.org/2020/formulas/mathematics/high-school/uhy7ymljjjy9r9mzqvbzhc4eru4dlpqqph.png)
Therefore, $57.625 will Mr. Roseanne pay for the beef
