Question

Two sporting goods stores are having discount sales on basketballs at one store a basketball is on sale for 25% off the regular price of 24.95 at the other store the same kind of basketball is on sale for 30% off the regular price of 25.80 what is the difference between the sale prices of the two stores

Answer 1

For this case we have:

Store 1:

We propose the following rule of three:

24.95 -----------> 100%

x -------------------> 25%

Where the variable x represents the discount amount:

$x = \frac {25 * 24.95} {100}\\x = 6.2375$

Thus, the price of the ball is:

$24.95-6.2375 = 18.7125$

Store 2:

We propose the following rule of three:

25.80 -----------> 100%

x -------------------> 30%

Where the variable x represents the discount amount:

$x = \frac {30 * 25.80} {100}\\x = 7.74$

Thus, the price of the ball is:

25.80-7.74 = 18.06

Thus, the price difference is:

$18.7125-18.06 = 0.6525$

ANswer:

0.6525

Answer 2

Answer:

0.66

Step-by-step explanation:

24.95 x 25%=6.23

24.94 - 6.23 = 18.72

25.80 x 30% = 7.74

25.80 - 7.74 = 18.06

18.72 -18 .06 = 0.66
