Each ticket costs $1.25
Jermaine bought 25 of them, which costs 25 x 1.25
25 x 1.25 = 31.25
He spent a total of $43.75 from the tickets and price of admission
we know the tickets cost 31.25, so the admission cost was 43.75 - 31.25
43.75 - 31.25 = $12.5
b) y = 1.25x + 12.5
Where y is the total cost, 1.25 is the price of each ticket, x is how many tickets a person bought, and 12.5 is the admission fee.
Hope it helps :)
60 dollars rounded but it's really answer is 59.80 dollars

The reciprocal of a number x is 1/x.
Let x = 1000
The reciprocal is 1/1000.
The easiest way is to graph it based upon the slope (m) and y-intercept (b), in the standard slope-intercept form: y = m (x) + b.
The line above intercepts the y-axis at y = -2, which is b. The slope (m) = rise/run = (y2-y1)/(x2-x1 ); so for the point (-4, 2) to (-6, 4) is:
(4-2)/(-6--4) = 2/(-6+4) = 2/-2 = -1.
So one form of the equation would be:
y = -1x - 2
Now the other form of an equation is point-slope: y-k = m (x-h), where the point is at (h, k)
and if we pick -5 for x (bc 5 it listed in 3 of the answers), the y at x=-5 looks like around +3
so we get: y-k = -1 (x--5)...
y-3 = -(x+5)... therefore D) is the correct answer:
