We have been given that you went to Walmart and spend $75. Of the total bill, $45.50 included non-taxable items.
Let us find the amount of taxable items by subtracting amount of non-taxable items from total bill.
We have been given that the rate of tax is 7.5% to the taxable items. To find the amount of tax, we will find 7.5% of $29.50.
Final amount of bill would be amount of bill plus amount of tax.
Therefore, final amount of bill would be 
.
Answer:
rate of motorboat: b
rate of current: c
So the rate the boat travels upstream is $b - c$, and the rate it travels downstream is $b + c$
Step-by-step explanation:
d = rt
200 = (b - c)\cdot 5
200 = (b + c)\cdot 4
b - c = 40
b + c = 50
Adding these equations, we get:
2b = 90
b = 45
So
c = 50 - 45 = 5
<u>Therefore the rate of the boat is 45kph, and the rate of the current is 5kph</u>
Hope this helps :)
Answer:
C
Step-by-step explanation:
One side is 60 so the other side is 60
X=20
4(20)-20=60
60=(4(20)-20)
60=80-20
60=60
