Find and review the slope formula.
The slope of a line segment that connects the points (a, b) and (c, d) is
d-b
m = --------------
c-a
Write out this formula for a=-3, b=-4, c=6 and d=-1.
We need to figure out how many more cans they need to bring. We figure this out by subtracting 403 from 1,000, which gives us 596 more cans. We now divide 596/28, to find how many each student would need to bring. This equals 21.3. You might want to mention that each student can't bring .3 of a can, so the answer could be 22 also.
Answer:
$8,500
Step-by-step explanation:
Interest = 5000 x 5 x 0.14
= 1000 x 0.14 x 25
= 140 x 25
= 3500
5000 + 3500 = 8500
