Answer:

1500

Step-by-step explanation:

24 month means 2 years ( N )

rate 15 pcpa ( R )

amount is 5000 ( P )

so by formula

interest = P×N×R/100

so ( I ) = 5000×2×15/100

so( I ) = 50×2×15 ....... ( here 100 ( 2 zero ) and 5000.( 2 zero ) got canceled

so ( I ) = 50×2×15

so ( I ) = 100×15

so ( I ) = 1500

Zarrin [17]

Answer:

20 gallons were used from the tank with the octane rating of 80.

Step-by-step explanation:

Given : One tank of gasoline has an octane rating of 140 and another tank of gasoline has an octane rating of 80. To obtain a mixture of 60 gallons with an octane rating of 120.

To find : How many gallons should be used from the tank with the octane rating of 80?

Solution : Let x be the volume of gas whose octane rating is 140 and

y be the volume of gas whose octane rating is 80.

Then, we form the equation as:

(1) $x\times140 + y\times80 = 60\times120$
