A) $1.17.
B) $1.22.
C) $1.29.
D) $1.34.

Answer 1

To find the cost of one candy bar, we need to set up a system of equations and solve for 'x'. Based on the given information, one candy bar costs $1.093, which can be rounded to $1.09.

Step-by-step explanation:

To find the cost of one candy bar, we need to set up a system of equations using the given information. Let's represent the cost of one candy bar as 'x'. From the first transaction, we have:

4x + 3(2x) = 10.93

Simplifying the equation, we get:

4x + 6x = 10.93

Combining like terms, we have:

10x = 10.93

Dividing both sides of the equation by 10, we find that:

x = 1.093

Therefore, one candy bar costs $1.093, which can be rounded to $1.09. The closest option provided is A) $1.17, but this is not the exact cost of one candy bar.
