at the neighborhood grocery, 4.5 pounds of ground beef cost $26.10. how much would it cost to buy 4.2 pounds…

Explanation:

Step1: Find the unit - price

First, find the cost per pound of ground beef. Let the cost per pound be $x$. We know that for 1.5 pounds, the cost is $26.10$. So, $x=\frac{26.10}{1.5}$. $x = 17.4$ dollars per pound.

Step2: Calculate the cost for 4.2 pounds

Now that we know the unit - price is $17.4$ dollars per pound, to find the cost of 4.2 pounds, we multiply the unit - price by the number of pounds. Let the cost of 4.2 pounds be $y$. Then $y=17.4\times4.2$. $y = 73.08$ dollars.

Answer:

$73.08$
