Answer:
The first one is 15.75 lbs or 15 3/4. The second one is 28 years old. The third one is$9.90 each t-shirt
Step-by-step explanation:
For the first one you multiply 18 by 14 and you get 252. Then there is 16 ounces in a pound so you divide by 16. Then you get 15.75. So that is your answer. The 2nd one you take 84 and multiply it by 1/6 then since she is twice the age of her sister you multiply by 2. so it would look like: 84 times 1/6= 14
14 times 2 = 28. So she is 28 years old. The third one you take 32 and subtract it by 12.20. You will be left with 19.8. Then both t-shirts cost the same so you would divide 19.8 by 2. You are left with 9.9. So the answer is $9.90. Sorry this took 10 minutes.

Well it is a simple percentage question that we have to solve.
As we know that William made 620 by baby sitting and we also know that he made 340 per cent more next year so we can simply calculate 340 per cent of 620 and then add that percentage value to 620 to calculate the final answer.
So 340 / 100 * 620 equals to 2108 so the final answer is 2108 + 620 which becomes 2728.
Since tax is 7.5% you need to subtract 7.5% from 300 witch would be
