A. 4 ounces
Step-by-step explanation:
Given that Elana paid $2.50 for 10 ounces of popcorn, let x be the amount popcorn a dollar will buy.
Thus we have:
$2.50 = 10 ounces
$1 = x
Cross multiply
$2.50 × x = 10 ounces × $1
Divide both sides by $2.50
($2.50 × x)/$2.50 = (10 ounces × $1)/$2.50
x = (10 ounces)/2.50
x = 4 ounces
Therefore, you can buy 4 ounces of popcorn per dollar
