Answer: $1,907.63
Explanation:
It is stated in the problem that the brokerage fee is $450 plus 1.15% (meaning 1.15% of $126,750). Hence the brokerage fee is computed as follows
(Brokerage fee) = $450 + (1.15% of $126,750)
= $450 + (0.0115)($126,750)
= $450 + $1,457.625
= $1,907.625
Since there is no half cents today, we round-off the brokerage fee to the nearest cent. Hence the brokerage fee is $1,907.63.
Note: In the computation of brokerage fee, we need to change 1.15% to decimal.
Answer:
y = -7 and x = -36
Step-by-step explanation:
x - 4y = -8
5y - 1 = x
→ Substitute 5y - 1 into x - 4y = -8
5y - 1 - 4y = -8
→ Simplify
y - 1 = -8
→ Add 1 to both sides
y = -7
→ Substitute y = -7 into 5y - 1
( 5 × -7 ) - 1 = -36
