A group of friends were working on a student film. They spent all their budget on props and equipment. They spent $693 on props, and 37% of the total budget on equipment. What was the total budget for their student film?
Answers
Answer:
$1100
Step-by-step explanation:
Let the total budget = b
amount spent on props + amount spent on equipment = total budget
If 37% of the budget was spent on equipment
The percentage spent on props = 100% - 37% = 63%
63% of the total budget is $693
the above sentence presented as an equation gives :
63/100 x b = 693
to find b, divide both sides of the equation by 100/63
b = $1100
Answer:
1100

Step-by-step explanation:
The x-intercept(s) of a function is the point(s) where the function intersects the x-axis, or the horizontal axis. If we look at the graph, we see that the function intersects the x-axis when [tex]x=3[/tex] (we know this because [tex]3[/tex] is directly in between [tex]2[/tex] and [tex]4[/tex]) and [tex]y=0[/tex], so the answer is [tex](3,0)[/tex].

What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
From the equation, the two points of Dave's line will be (0, 6) and (2, 9). Then the equation is given as,
(y - 6)[(9 - 6) / (2 - 0)](x - 0)
y = 1.5x + 6
From the equation, the two points of Andrew's line will be (0, 3) and (1, 5). Then the equation is given as,
(y - 3) = [(5 - 3) / (1 - 0)](x - 0)
y = 2x + 3
The number of hours when the amount Andrew and dave pay for the rentals be equal will be calculated as,
2x + 3 = 1.5x + 6
0.5x = 3
x = 6 hours
The number of hours when the sum Andrew and dave pay for the rentals be equivalent will be 6 hours.
