Question

At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual. What percentage of the usual price is the savings?

Answer 1

Answer: 15%

Step-by-step explanation:

Given : At a hardware store, a tool set normally costs $80.

i.e. Usual price of a tool set = $80

During a sale this week, the tool set costs $12 less than usual.

i.e.  savings = $12

Now, the percentage of the usual price is the savings is given by :-

$\dfrac{\text{Savings}}{\text{Usual price}}\times100\%\\\\=\dfrac{12}{80}\times100\%\\\\=\dfrac{1200}{80}\%=15\%$

Hence, the percentage of the usual price is the savings = 15%

Answer 2

12. = x
80 100 and u have to cross multiply

80x = 1200
80. 80

then divide 1200÷80=15
