A customer calculated the cost of a new jacket, c, including a 7% sales
tax, by multiplying 0.07 times the cost of the jacket and adding the
product to the cost of the jacket. What is another way to calculate the
price including tax? What expression represents the total cost?​

Respuesta :

we can put it into one step by multiplying the cost by 1.07 which basically takes into account the old cost of the jacket and the tax

the expression is
original amount * decimal multiplier (1.07) = new amount
