Final answer:
To find the cost of a blueberry pie and a sweet potato pie, we can set up and solve a system of equations using the given information.
Step-by-step explanation:
To find the cost of a blueberry pie and a sweet potato pie, we need to set up a system of equations using the information given. Let x represent the cost of a blueberry pie and y represent the cost of a sweet potato pie. From the given information, we can write the following equations:
Isaiah: 12x + 6y = 180
Kamani: x + 12y = 130
To solve this system of equations, we can use the method of substitution or elimination. Let's use the substitution method. From Kamani's equation, we can isolate x:
x = 130 - 12y
Substituting this value of x into Isaiah's equation, we get:
12(130 - 12y) + 6y = 180
Simplifying, we have:
1560 - 144y + 6y = 180
Combining like terms, we get:
-138y = -1380
Dividing both sides by -138, we find that:
y = 10
Substituting this value of y back into Kamani's equation, we can solve for x:
x + 12(10) = 130
x + 120 = 130
Subtracting 120 from both sides, we get:
x = 10
Therefore, the cost of a blueberry pie is $10 and the cost of a sweet potato pie is $10.
