Question

At a hardware store a tool set normally cost $80 during the sale this week the tools that cost $12 less than usual what percentage of the usual price is a savings explain or show your reasoning

Answer 1

15 % of usual price is a savings

Solution:

Given that tool set normally cost $80

During the sale this week the tools that cost $12 less than usual

To find: what percentage of the usual price is a savings

From given information,

Usual price of tool set = $ 80

Given that tools that cost $12 less than usual which means she saved $ 12

Savings = $ 12

To find what percentage of the usual price is a savings, we can solve by framing a expression,

Let "x" be the required percentage

Then x % of percentage is equal to savings price

x % of usual price = savings price

x % of 80 = 12

$\frac{x}{100} \times 80 = 12\\\\x = \frac{12 \times 100}{80}\\\\x = 15 \%$

Therefore 15 % of usual price is a savings
