Understanding inequalities and equations
To expand our knowledge in equations solving, we need to solve some verbal problems. With verbal problems we mean problems that we need to translate into an equation by ourselves.
Example
Leonard earns $60 a day. After a few days Leonard has earned $240. How many days has Leonard worked? We denote the number of days he has worked as x.
$$\$60x=\$240$$
$$\frac{\$60x}{60}=\frac{\$240}{60}$$
$$x=4$$
To earn $240 Leonard has to work 4 days.
Video lesson
Margaret is paying $1,500 in rent for her apartment every month. Margaret won $12,000 in Vegas and wondering how many rent she can afford to pay with this winning?
