There is 17% error in the guess.
Step-by-step explanation:
Given,
Number of marbles in jar = Exact value = 240
Closest guess = Approx Value = 280
Percent error = 
Percent error = 
Percent error = 
Percent error = 
Rounding off to nearest whole percent
Percent error = 17%

We want to find the x and y-intercepts for the given linear equation.
The x-intercept is x = 12, and the y-intercept is y = 6.
We know that x represents the number of children and y the number of adults that can attend the rodeo for $180.
The x-intercept is defined as the x-value when y = 0. So we just need to replace y by 0 and solve for x:
15*x + 30*0 = 180
15*x = 180
x = 180/15 = 12
Meaning that if there are no adults, 12 children can attend to the rodeo for $180.
The y-intercept is the y-value when x = 0, similarly to before, this is computed as:
15*0 + 30*y = 180
30*y = 180
y = 180/30 = 6
This means that if only adults go, 6 of them can go for $180.

I would first put these two points on a graph, they are pretty far apart but i know that the answer is on this question somewhere, so we start counting the amount of squares it takes to get from point A to point B, I got an answer result of 7 squares, so I conclude that the answer is 7
