Answer:
$972 interest made
Step-by-step explanation:
p x ir x t =interest
800x.0675x18=972
2(3+y)+y=3
6+3y=3
Y=-1
Substitute to solve for x
X=3-1
X=2
Factor the quadratic equation (3x-4)(x+3). Then set the factors equal to zero.
3x-4=0, solve to get 4/3
x+3=0 x=-3
y = .0775x + 700
y = .0775(4,000) + 700
y = 310 + 700
y = 1,010
