A store reduces the price of a 50 inch television by 20% on Thursday and then reduces that price by another 15% on Sunday. If the final price of the television is 170, what was the original price before Thursday's discount?

the original price before Thursday's discount is $250

Step-by-step explanation:

Let x represent the original price before Thursday's discount.

The store reduces the price of a 50 inch television by 20% on Thursday. It means that the amount by which it was reduced is

20/100 × x = 0.2x

The new price on Thursday would be

x - 0.2x = 0.8x

The store then reduces that price by another 15% on Sunday. It means that the amount by which it was reduced is

15/100 × 0.8x = 0.12x

The new price on Sunday would be

0.8 - 0.12 = 0.68x

If the final price of the television is 170, it means that

0.68x = 170

x = 170/0.68

x = 250

what's that

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
