Let [tex] c [/tex] be the price of an ear of corn. So, six ears of corn cost [tex] 6c [/tex]. We thus have
[tex] 6c = 1.80 [/tex]
Divide both sides by 6 to get
[tex] c = \dfrac{1.80}{6} = 0.3 [/tex]
Answer:
The cost was $0.30 per ear of corn.
Step-by-step explanation:
We assume that exist a linear relationship between the amount of ears of corn and the price.We also assume that it is a direct linear relationship. This means that a greater number of ears of corn imply a greater price. Now we can write this mathematically :
[tex]\frac{(6)EarsOfCorn}{(1.80)Dollars}=\frac{(1)EarOfCorn}{x}[/tex]
Solving in terms of x :
[tex]x=\frac{(1)EarOfCorn.(1.80)Dollars}{(6)EarsOfCorn}=0.3Dollars[/tex]
Therefore, the cost per ear of corn is $0.30
