Step-by-step explanation:
Amount originally in the cup = amount she drank + amount remaining
= 17 * 4.5 + 148.5
= 76.5 + 148.5
= 225 milliliters.
The time she takes to drink the 148.5 mL = 148.5 / 4.5
= 33 seconds.
So time to drink it all = 17 +33 = 50 seconds.
76.15 - 43.49 = 32.66
It costed him $32.66 to make the homemade jewelry.

Step-by-step explanation:
The selling price is $495.
The first washing machine:
- is marked down by 30%
$495 - 100%
$x - 100% - 30% = 70%
Find the value of x:
The second washing machine:
- is marked down by 20% with an additional 10% off
$495 - 100%
$y - 100% - 20% = 80%
Find y:
Now,
$396 - 100%
$z - 100% - 10% = 90%
Find z:
Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.
