Answer:
$1 would buy 1.25lbs of bananas
Step-by-step explanation:
In order to find the amount $1 will buy, we need to create a proportion. One the left side we can use the unit rate. On the right we use the unknown quantity.
6.5lbs/$5.20 = xlbs/$1.00
Now we cross multiply
6.5 * 1.00 = 5.20 * x
6.5 = 5.20x
1.25 = x
