Answer:
Slope =
Step-by-step explanation:
(-9, -8) & (-15 , -16)
Slope =
A = deposit at US bank
b = deposit at 7/4 bank
c = deposit at Catch bank.
we know her total is 3886, thus a + b + c = 3886.
now, we know whatever "b" is, the amount at US bank, "a", is 3 times that much, thus a = 3b.
(3b) + b + c = 3886.
whatever% of anything, is just (whatever/100) * anything.
we know Catch bank gets 45% of whatever the sum of the other two is, well, US bank gets "3b", 7/4 bank gets "b", their total is 3b + b = 4b, and Catch bank gets 45% of that, (45/100) * 4b
how much is it for the Catch bank? well, (45/100) * 4(670).
