Yo i need help wit 17 and 18 i’ll give u a brainliest you please

Answer 1

Answer:

17. See below

18. 750

Step-by-step explanation:

17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.

18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:

$y=0.5x+125$

Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:

$500=0.5x+125$

$500-125=0.5x$

$375=0.5x$

$\frac{375}{0.5} =x$

$375*2=x$

$750=x$

Thus, 750 lollipops must be sold.
