If the charges for the first company are cheaper, then Multiply this inequality by 1,000: Mathematics Step-by-step answer P Answered by PhD 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 Mathematics Step-by-step answer P Answered by PhD 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 Mathematics Step-by-step answer P Answered by PhD 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 Mathematics Step-by-step answer P Answered by PhD The wood before starting =12 feet Left wood=6 feet Wood used till now=12-6=6 feet Picture frame built till now= 6/(3/4) =8 pieces Therefore, till now 8 pieces have been made. Mathematics Step-by-step answer P Answered by PhD Salesperson will make 6% of 1800 =(6/100)*1800 =108 Salesperson will make$108 in $1800 sales Mathematics Step-by-step answer P Answered by PhD The answer is in the image Mathematics Step-by-step answer P Answered by PhD 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 Mathematics Step-by-step answer P Answered by PhD Given height of gymnasium is 5/6 height of 30 foot ball therefore height of gymnasium=5/6 * 30 =25 feet Mathematics Step-by-step answer P Answered by PhD 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%
