Each card she sells cost $3.25.
y = 3.25s
y = 3.25(4) = 13
Each card she buys cost $5.50.
y = 5.25b
y = 5.25(7) = 38.5
She spent 38.5 dollars in total. However, you need to subtract the money she earned by the total cost.
38.5 - 13 = 25.5
She paid 25.5 dollars out of her own pocket, including the money she earned from selling cards she paid 38.5 dollars.
So the answer is "She spent $25.50"
Let me know if it's correct
Answer:
f(x) = y + (x*p)
Step-by-step explanation:
Since we are not given actual values we will need to make the function with only variables. Each variable will represent the following...
Fixed Cost: y
Cost per charm: p
Number of charms: x
Therefore, using the variables mentioned above we can combine them into the following linear function using the number of charms as our main input for our function...
f(x) = y + (x*p)
Formula is 2(wl+hl+hw)
and dimensions are doubled so 5 is 10, 4 is 8, and 3 is 6.
2[(8x6)+(6x10)+(6x8)]
=376 cm^3
Step-by-step explanation:
5(m – 8) - 4(m – 7)
5m-40-4m+28
m -12
