Answer:

$\$15.60$

Step-by-step explanation:

Mr. Rand initially starts with 18 pounds of meat. After cutting steaks weighing pound 15 ounces, 3 and 1/8 pounds, and 4 and 1/2 pounds, he will have:

$18-1.9375-3.125-4.5=8.4375$ pounds of meat left (there are 16 ounces in a pound).

Since he sells patties that measure 9 ounces, convert 8.4375 pounds to ounces:

$8.4375\text{ lbs}\cdot 16\text{ oz/lb}=135\text{ oz}$

Because each patty is 9 ounces, he can make $\frac{135}{9}=15$ patties. He sells 3 of them for $3.12, meaning the price per patty is $\frac{\$ 3.12}{3}=\$1.04$ .
