Answer:
$0.70 per ear of corn
Step-by-step explanation:
Let c = Ear of corn
Let b = pound of bananas
First shopper:
7c + 6b = $5.15
Second Shopper:
4c + 1b = $1.85
Solve one equation for b since you are solving for c:
4c + 1b = $1.85
b = $1.85 - 4c
Substitute into other equation:
7c + 6b = $5.15 <--- b = $1.85 - 4c
7c + 6 ($1.85 - 4c) = $5.15
7c + $11.1 - 24c = $5.15
-17c + $11.1 <em>- $11.1</em> = $5.15 <em>- $11.1</em>
-17c <em>/-17</em> = -$11.85 <em>/-17</em>
c = $0.70 per ear of corn

<h3>What are rational numbers?</h3>
A rational number is a type of real number, in the form of;
p/q
where
- q is not equal to zero
- p is a whole number.
It is important to note that any fraction with a denominators not equal to zero is a rational number
Examples of rational numbers are 1/2, 1/5, 3/4, and so on.
Also, the number “0” is also a rational number, but when it is represented forms such as 0/1, 0/2, 0/3, etc. But, 1/0, 2/0, 3/0, etc. It is not rational
- 57/ 7 is a rational number
Thus, the number -57/ 7 is a rational number.

No, it should not give exactly the right amount because numbers will have to be rounded because US dollars only go to the hundredths place making the final number slightly different than the exact value would be.
