Transcript
| 00:0-1 | Hi , I'm Danny and welcome to a neuronal JR | |
| 00:02 | . Today we're going to learn about solving inequalities using | |
| 00:05 | multiplication . For example , one of the questions once | |
| 00:27 | away , right and soul cost $1.50 a 30 day | |
| 00:32 | pass cost $48 . A male school student wants to | |
| 00:36 | know How many one way right you must take for | |
| 00:40 | the 30 day pass to be a better deal , | |
| 00:42 | right ? And solvent equipped inequality to find a number | |
| 00:45 | of one way right you must take for the 30 | |
| 00:47 | day pass to be a better deal . The thing | |
| 00:49 | we don't know about this problem is the number of | |
| 00:51 | rights which are going to call our , So we | |
| 00:54 | have to make the cost of the 30 day pass | |
| 00:57 | to be a better deal . So the cost of | |
| 01:00 | the 30 day passes to me less than the cost | |
| 01:03 | of when we passes . The cost of 30 impacts | |
| 01:06 | is $48 . And The cost of the one way | |
| 01:11 | passage has to be $1 , are . So this | |
| 01:19 | would have to become 40 would have to be less | |
| 01:22 | than the $1 50 cents are . Now let's solve | |
| 01:27 | the inequality . So first we have to divide this | |
| 01:31 | by $1.50 to make to get our alone . So | |
| 01:37 | , but if you do it to one side to | |
| 01:39 | the other , so you divide 48 $51.50 this would | |
| 01:45 | become our , which has to be greater than 32 | |
| 01:51 | when we passes For the 30 day pass to be | |
| 01:54 | a better deal . You have to ride the subway | |
| 01:57 | more than 32 times you want to try on your | |
| 02:00 | own . Thank you for watching . And if you | |
