Answer:
TRUE
Step-by-step explanation:
Answer:
y = 3x + 62
Step-by-step explanation:
Trend line equation in the form :
y = mx + b
m = slope
b = intercept
Using the points :
(0, 62) ; (6, 80)
Slope, m = Rise / Run = (y2-y1) / (x2 - x1)
y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0
m = (80 - 62) / (6 - 0)
m = 18 / 6
m = 3
Intercept, b = value of y when x = 0
(0, 62) ; hence, b = 62
y = 3x + b
y = 3x + 62

Answer: $611</h3>
Work Shown:
30% of 470 = 0.30*470 = 141
The value goes up by $141, so the answer would be 470+141 = $611
A slight shortcut would be to say
1.30*470 = 611
This works because 1.30 = 1 + 0.30 = 100% + 30%
