Question

ramir is hoping to save up for a new bike. the cheapest one he has found is 100$. he has 25$ if he can save 15$ each week haw man weeks at least should he save for write an inequality for this situation and then solve it

Answer 1

`25+15x\geq100` where x=weeks x=5 or more

Explanation:

he needs $100 dollars, so you have to be greater or equal to that, so that is where you start. he already has 25 dollars, so you add that into the equation opposite the 100. you then show that he earns $15 dollars per week, hence 15x, you can then solve by subtracting the 25 over, wich gives you
`15x\geq 75` you then divide 75 by 15 and get 5 weeks.
