The ratio table shows the costs for different amounts of bird seed. Find the unit rate in dollars per pound.

Maru [420]

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,

$\frac{5}{11.5}=\frac{50}{115}=\frac{10}{23}\\\\\frac{10}{23}=\frac{10}{23}\\\\\frac{15}{34.50}=\frac{1500}{3450}=\frac{150}{345}=\frac{30}{69}=\frac{10}{23}\\\\\frac{20}{46}=\frac{10}{23}$

Therefore,

$\frac{5}{11.5}=\frac{10}{23}=\frac{15}{34.50}=\frac{20}{46}$

Cost of 10 pounds = 23 dollars

So, cost of 1 pound = $\frac{23}{10}=2.3$ dollars
