A T-shirt that costs $14 without tax costs $14.98 with tax. What
is the sales tax percent?

Respuesta :

Answer:

7%

Step-by-step explanation:

14+Sale tax=14.98

14.98-14=sale tax

14.98-14=0.98

0.98 is the sale tax now we need to find the percent

Let represent t percent

14 of t%=0.98

14*t/100=0.98

we need to use inverse operation to isolate T on one side so if its multiplication we need to do division on both sides to un-due multiplication.

So to move 100 we need to multiply on both sides and we will get

14*t=0.98*100

0.98*100=98

14*t=98

to move 14 we need to divide

14/14=1

we dont need to put 1t becuase t is =1

so we just write it as t

98/14=7

t=7

so Sale tax percent is 7%
