Martin needs 3.25 gallons of red paint for his small barn and 1.25 gallons of paint for his shed. he spends $81 on paint. how much does the paint cost per gallon?

18

Step-by-step explanation:

3.25 + 1.25 = 4.5

81 / 4.5 = 18

First Option is correct.

Step-by-step explanation:

Since we have given that

Number of gallons of red paint for his small barn is needed = 3.25

Number of gallons of paint for his shed = 1.25

Total number of gallons is given by

Total amount he spent on paint = $81

So, Cost per gallon is given by

So, Cost per gallon = $18

Hence, First Option is correct.

3.25 + 1.25 = 4.50 gallons

81/4.5 = 18 dollars per gallon

The answer is in the image 

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
