To make a profit of $10, the box should sell out for $30+$10=$40. Divided by 50 bars, that's 80 cents per bar.
A. Perpendicular!
Because they cross with a 90 degree angle :]
You find a common greatest factor, which in this case is 7. 1/4 is your answer.
No, because if you substitute (4, -2) into x and y in each equation, they are not the same as the value on the right side of the equation.
2(4) + 4(-2) = - 2
8 + -8 = -2
0 = -2 <---- this is not correct.
-4(4) + -2 = -14
-16 + -2 = -14
-18 = -14 <----- this is not correct.
Answer:
The final cost is 1.07($17.15) = $18.35
Step-by-step explanation:
If the discount is 30%, we can find the discounted price by taking 70% of the original price (since 100% - 30% = 70%). Substitute the equivalent 0.70 to calculate the discount price: 0.70($24.50) = $17.15. This is the discounted price.
The final cost is $17.15 times 1.07, which includes the discounted price plus the 7% tax. That final cost is 1.07($17.15) = $18.35.
