A company finds that there is a linear relationship between the amount of money that it spends on advertising and the number of
units it sells. If it spends no money on advertising, it sells 250 units. For each additional $4000 spent, an additional 25 units are sold. If x is the amount of money that the company spends on advertising, find a formula for y, the number of units sold as a function of x.
The formula for the equation of y, the number of units sold as a function of x is y = 0.00625x + 250
<h3>How to illustrate the equation?</h3>
From the information given, when the company spends no money on advertising, it sells 250 units and for each additional $4000 spent, an additional 25 units are sold.
If Jiri is x, Pamela is x -5, and tehri ages combined would be 35 so; x + x-5 = 35 collect the like terms 2x-5 = 35 add five to both sides 2x= 40 divide both sides by 2 x=20 Jiri's age is 20
I don’t think there is anything wrong with the coming there is just a 50% chance that It would land on tails and there’s a 50% chance that it will land on heads ♀️☺️
