Answer:
C. t = 0.05125c
Step-by-step explanation:
First we have to understand the meaning of % sign. It is called percent or percentage. Where cent means 100. Now all we know that 100 cents make one dollar, that is why these 100 smaller units are called as cents.
Now if sales tax is 5.125 percent, remember that if there is $100 capital amount, it will be $5.125 tax.
Now how much would it be for $1?
simply, it will be $0.05125
Now for equation in option C
t = 0.05125 x 1
t = 0.05125
here you can see that the equation is satisfied.
So from this we can establish the equation that for any cost, the relation between tax and cost will be:
t = 0.05125c
