The equation that could be used to find the value of c is 3.8c - 0.75 = 2.67. So, the correct answer is option E:
How to find the equation that represents the cost
To find the equation that represents the cost of the fruit in dollars per pound, we can start by setting up the equation based on the given information.
Let's assume the cost per pound of both plums and bananas is represented by the variable c.
The cost of 2.25 pounds of plums is 2.25c, and the cost of 1.55 pounds of bananas is 1.55c.
After applying a coupon discount of 75 cents (0.75 dollars), the total cost is $2.67.
Therefore, the equation that represents the given information is:
2.25c + 1.55c - 0.75 = 2.67
Simplifying the equation:
3.8c - 0.75 = 2.67
So, the correct answer is option E:
3.8c - 0.75 = 2.67
