Answer:
2.3 dollars
Step-by-step explanation:
Given:
Ratio table that shows the costs for different amounts of bird seed
To find: the unit rate in dollars per pound
Solution:
Amount (pounds) 5 10 15 20
Cost (dollars) 11.5 23 34.50 46
Here,
[tex]\frac{5}{11.5}=\frac{50}{115}=\frac{10}{23}\\\\\frac{10}{23}=\frac{10}{23}\\\\\frac{15}{34.50}=\frac{1500}{3450}=\frac{150}{345}=\frac{30}{69}=\frac{10}{23}\\\\\frac{20}{46}=\frac{10}{23}[/tex]
Therefore,
[tex]\frac{5}{11.5}=\frac{10}{23}=\frac{15}{34.50}=\frac{20}{46}[/tex]
Cost of 10 pounds = 23 dollars
So, cost of 1 pound = [tex]\frac{23}{10}=2.3[/tex] dollars
