Hello,

The two lights flash at the same time every 18 min
at 8:00 h=480 min =480+0*36
at 8:36 h=516 min =480+1*36
...
54 is not divisible by 36
60+12=72 = 2*36 yes
60+24=84 not
120+24=4*36 yes
180+18=198 not

So 2 times are correct 9:12 and 10:24

The original price of a skateboard was $85. The owner of the store

lora16 [44]

Answer:

$\$68$

Step-by-step explanation:

1. Approach

To solve this problem, one wants to find the price of a product after its discount has been applied. The discount is 20% off, so the new price of the item is 80% of its original price (percent is out of 100 so if a an item is 20% off, it is 100 - 20 = 80; 80% the original price). To calculate the percent cost, one would divide the percent value by 100, and then multiply it by the price of the item.

2. Solving

The price of the new item is 80% of the price of the original item. To calculate the percent cost, cent, one would divide the percent value by 100, and then multiply it by the price of the item.

Therefore, the equation that will be formed is,

$price * \frac{percent}{100}$

Substitute,

$85 * \frac{80}{100}$

Simplify,

$85 * 0.8\\\\= 68$
