Answer:
$ 37.642
Step-by-step explanation:
Total Bill : $ 32.45
Tip : 16% of the bill.
= 16% x 32.45
=32.45 x (16/100)
= $ 5.192
hence ,
Total bill = Tip + bill charged
= 5.192 + 32.45
= $ 37.642
Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
This is so easy okay just make sure if it’s true or not
