Answer: $ 5,850
Step-by-step explanation:
Let the original amount in May be 
, since the amount increases by 30% in June , this means that the amount in June will be 130% of .
Amount in June = 1.3
Also , it decreases by 10% from June to July , that is the amount in July will be 90% of 1.3
Amount = 1.17
The difference in the amount of sales between May and July is $7,650. That is
divide through by 0.17
Therefore :
Amount in May = $
Amount in June = 
= $ 
Amount in July = 1.17 ( 45,000 ) = $52,650
the difference in the amount of sales between June and July will be
$58,500 - $ 52 , 650 = $ 5,850
Answer: Both trains would meet at 1 pm
Step-by-step explanation:
Let t represent the time at which both trains will pass each other.
The distance between the cities is 360 miles. This means that by the time both trains meet, the total distance covered would be 360 miles.
Distance = speed × time
The freight train is travelling at 50 mph. Distance covered by the freight train in t hours is 50t.
The passenger train is travelling at 70 mph. Distance covered by the passenger train in t hours is 70t.
Since the total distance covered is 360 miles, it means that
50t + 70t = 360
120t = 360
t = 360/120
t = 3 hours
Both trains would meet at 1 pm
Answer:
A
Step-by-step explanation:
The volume of the tank is (70 cm)³ = 343,000 cm³.
Now,
1 mL = 1 cm³
1 L = 1000 mL
so we convert the given rate to
Then the time it will take to fill up the tank is
