Answer: Andrew
Given:
<span>$750- Andrew’s mutual fund every year
until the 10th year</span>
<span>$9000 – Stephanie’s mutual fund in the
10th year</span>
5%- average percent rate of return
To determine who will have the larger
mutual fund balance in 20 years, we will use the simple interest formula which
is the interest gained only on the principal.
Let X= the principal amount of Andrew’s
mutual fund after 20 years
X=(750+750(.05))*20
X =(750+37.50)*20
X=787.50(20)
X=15,750 in 20 years
<span>Let Y=principal amount of Stepanie’s mutual
fund after another 10th year</span>
Y=9000+(9000(.05)*10)
Y=9000+(450*10)
Y=9000+4500
Y=13,500
<span>X>Y so
Andrew has the greater mutual balance. </span>
Answer:
16 chocolate bars
Explanation:
first subtract 15-3=12
the equation would be 12x/0.75 and x represents the number of chocolate bars
divide 12/0.75=16
so the answer is 16 chocolate bars
Amount of money Ann earned this week = Amount of money earned in 1hour × Number of Hours she worked
Amount of money Ann earned this week = (4x + 3) × (2x - 1)
= (4x + 3) (2x - 1)
{Draw lines like rainbows to let yourself know which numbers to multiply by}
= (4x × 2x) + [4x × (-1)] + (3 × 2x) + [3 × (-1)]
{Always remember to put in the negative signs if the number if negative}
= 6x^2 + (-4x) + 6x + (-3)
= 6x^2 - 4x + 6x - 3
{Simplify}
= 6x^2 + 2x - 3
