KNOWLEDGE IS POWER: if you know more than everyone else, you will be the brightest kid in the class

Kwok likes to eat. I will give $25 to buy lunch in a (ONE) fast food restaurant

- no coupon, no Uber, no buy one get one free

- spend as close to $25 as possible without going over

- cannot buy more than one of the same item

- calculate the HST (13%)

- send your answer to kwokhomework@gmail.com

- include the name of restaurant, the price of each item, and calculate the tax and total

- must be less than $25.01

Sample answer

e.g. Wok with Kwok

Sweet and Sour Chicken $12.05

Shrimp Fried Rice $8.07

Spring Roll $2.00

Water Free

Total food 12.05+8.07+2.00 = $22.12

Tax 22.12 x 0.13 = $2.88

Total payable 22.12 + 2.88 = $25.00

Common Corrosive substances in your home: bleach, toilet bowl cleaner, vinegar
corrode or burn skin (can bleed or get infected easily)
Don’t drink vinegar (it corrodes your stomach lining), but you can add to fries and other food
If you put bleach directly on a shirt, it will make a hole in the shirt within an hour
Usually, people dilute bleach with water first before putting it into the washing machine (1 part bleach, 5+ parts water)

Compressed gas cylinder: if it is dropped to the ground or the top cap is loosened or broken, it will fly like a rocket. This will break doors, walls and your legs.
These gas cylinders must be securely placed so that they don’t drop onto the floor.
Some patients need oxygen tanks to supply oxygen for them to breathe.

Biohazard materials: used syringes contain small droplets of blood (which can carry diseases, viruses, drugs and other funny things)
Next time when you go and get a flu/COVID shot, your doctor puts the used syringe in a yellow box, and the box has the biohazard label.
These syringes will be incinerated
Never pick up a used syringe from the park or parking lot. Tell a caretaker or teacher if you see one from the schoolyard
