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

Here,
tip=18%of $32
tip=(18/100)*32
=0.18*32
=$5.76
Total payment=32+5.76=$37.76
tip=18% of 75.45
=18/100 * 75.45 = $13.581
Tip = $13.581
Let the father's age be x and son's be y
10 years before-
Father age=x-10
sons age=y-10
Given,
x-10=10(y-10)
x-10=10y-100
Given present age of father=40
therefore,
x=40
40-10=10y-100
10y-100=30
10y=130
y=130/10
y=13
Therefore present age of son=13years
Given height of gymnasium is 5/6 height of 30 foot ball

Cost before sale tax=$46.00
Cost after including tax=$48.76
Sale tax=$48.76-46.00
=$2.76
we know,
sale tax=((sales tax rate)/100) * cost before sale tax
2.76=((sales tax rate)/100) *46.00
sale tax rate=(2.76*100)/46
=276/46
=6%
There fore sales tax rate=6%
It will provide an instant answer!
