2. Distributive property (multiplying the -2 to the items in parentheses)
3. Subtraction property (subtracting 8 from 3)
4. Addition property (adding 5 to both sides)
5. -4x = 16 (subtracting 6x from both sides)
6. x = -4 (dividing both sides by -4)
The first one is A while the second one is B
5 + 3(2x +4) + 6
5 + 6x + 12 + 6
5 + 12 + 6 +6x
= 23 + 6x
Answer:
Kyle would save more using his 15% off of $1000 coupon.
Explanation:
15 ÷ 100 • 1000 = 150
1000 - 150 = $850
$150 is the amount the 15% coupon took off.
$850 is the amount Kyle will pay.
vs.
1000 - 80 = $920
A) $3500*0.055 = $192.50 . . . . the interest paid each year
B) The problem makes no mention of compounding, so we assume simple interest is paid. (Most accounts do not work this way.)
.. at the end of 1 year, 3500 +192.50 = $3692.50
.. at the end of year 2, 3692.50 +192.50 = $3885.00
.. at the end of year 3, 3885.00 +192.50 = $4077.50
.. at the end of year 4, 4077.50 +192.50 = $4270.00
.. at the end of year 5, 4270.00 +192.50 = $4462.50
