Answer:
the answer would be 4
Step-by-step explanation:
because 120 divided by 30 is 4
Answer: The system of equations represents the constraints in this situation are:
s + h = 40
$18s + $14h = $700
The above equations are known as simultaneous equations. 40 scarves and hats were sold, this can be represented with this equation:
number of hats sold + number of scarves sold = 40
s + h = 40
The total amount made from the sales is the sum of the total amount made from the sale of the hats and the total amount made from the sale of the scarves. This can be represented with this equation:
($18 x s) + ($14 x h) = $700
