X + y = 23000
x.08 + y.09 = 2040
x = 23000 - y
(23000 - y) .08 + y.09 = 2040
1840 - .08y + .09y = 2040
Simplify
.01y = 200
Simplify
Y = 20000
X + 20000 = 23000
X = 3000
CHECK: .08x + .09(20000) = 2040
.08x + 1800 = 2040
Simply .08x = 240
X = 3000

Answer:
negative because any positive number multiplied by a negative number will be negative, the only way to make it positive is to multiply a negative number by another negative number.
Step-by-step explanation:

Cross multiply:
75*? = 42*100
⇒ ? = 42*100/75= 56
The original price of the sweater was $56.
