Answer: Mark up percent = 20%
Step-by-step explanation:
Given: Cost price of each T-shirt = $5.00
Amount required = $450
Total students = 75
Market price for each T-shirt to raise the required amount = (Amount required ) ÷ 75
= $450 ÷ 75
= $ 6
Mark up percent = 

Hence, Mark up percent = 20%
Answer:
not sure
Step-by-step explanation:
Let w be the additional watts you can add on the circuit.
1100 + w < 1800 (write the inequality)
-1100 -1100 ( - 1100 from each side)
w < 700 (simplify)
ANSWER:
You can add up to 700 watts to the circuit, which means that you can also plug in the clock radio and the blender.
LOOK BACK:
You can check that your answer is correct by adding the numbers of watts used by the microwave oven, clock radio and blender.
1100 + 50 + 300 = 1450
The circuit will not overload because the total wattage is less than 1800 watts.
