Answer:
$141.44
Step-by-step explanation:
- $17.68 each plate
- There are 8 plates
17.68 times 8 = $141.44
The slope of y = -x is m = -1. Thus, starting with the slope-intercept form y = mx + b, we substitute -1 for m, 8 for x and 2 for y, to determine the vaue of b:
2 = -1(8) + b, or 10 = b. Then the equation of the line parallel to y = -x and passing thru (8,2) is:
y = -x + 10.
So we know that 125% more will attend because it's 100% of the people from last year plus an additional 25%. This when converted to a decimal would be 1.25 (divide percent by 100). Then simply multiply the number of people from last year by 1.25.
660 × 1.25 = 825
You ca mb also break it up and do the 25% separately.
660 × .25 = 165
This value would then need to be added to last years amount because it's that many people *more*.
660 + 165 = 825
X= 150
