Answer:
2nd one
Step-by-step explanation:
Answer: 14,575
Step-by-step explanation:
85(2) 0.4x = 6000 Multiply 85 times 2
170 + 0.4x = 6000 Subtract 170 from both sides
0.4x = 5830 Divide 5830 by 0.4
x = 14,575
First understand that this is a linear graph. Find 2 points on the graph. We can use (0,1) and (3,-3).
Look at how much the x increases, in this case the x value increases by 0+3, so 3.
Then see how much the y value increases (make sure to evaluate them in the same order) 1 + (-3) = -2.
So you know that the y value decreases by 2 units for every 3 unit increase in x. Therefore the slope is y=(-2/3)x
Then figure out what you add to the end. The y intercept is (0,1), so add 1 to the end of y=(-2/3)x to move it up.
Your resulting eq is y=(-2/3)x+1
500 - 116 = 384 left to collect
384 divided into 3 weeks = 128
They must collect $128 per week in order to reach their goal of $500.
