Let cost of item before tax is $x.
Rate of sales tax = 2.5% = 2.5/100 = 0.025
Cost of groceries with tax = x+0.025x = 1.025x
Total cost of groceries= $1.60
1.025x = 1.60
x = 1.6/1.025
x = $1.56
So cost of groceries before sales tax= $1.56
For 1 flavor there are 9 topping
Therefore, for 5 different flavors there will be 5*9 choices
No of choices= 5*9
=45
For every 8 cars there are 7 trucks
Therefore,

Answer is B)8:7
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
The answer is in the image
F=ma
where F=force
m=mass
a=acceleration
Here,
F=4300
a=3.3m/s2
m=F/a
=4300/3.3
=1303.03kg
Approximately it is aqual to 1300kg
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.
Area of rectangle= L*b
here,
L=12.4 cm
b= 8.8 cm
A= L*b
= 12.4 * 8.8 = 109.12 cm^2
It will provide an instant answer!
