interest = principal x rate x time
interest = 1344-1200 = 144
principal = 1200
rate = 8% = .08
144 = 1200 x .08 x Time
Time = 1.5 yrs
Answer:
D
Step-by-step explanation:
Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.
<u>Numerical Expression</u>
"Difference" indicates that we'll be subtracting 13 from 48.
48 - 13 = 35
<u>Algebraic Expression</u>
Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.
48 - 13 = d
35 = d
<span>If you would like to know how many of each type
of ticket were sold, you can calculate this using the following two
equations:
a ... the number of drakes fan club tickets
s ... the number of no members tickets
$550 = a * $20 + s * $25 ... 550 = 20 * a + 25 * s
a + s = 25 ... a = 25 - s
__________________
</span>550 = 20 * a + 25 * s
<span>
550 = 20 * (25 - s) + 25 * s</span>
550 = 20 * 25 - 20 * s + 25 * s
550 - 20 * 25 = 5 * s
550 - 500 = 5 * s /5
s = 50 / 5
s = 10 tickets
<span>a = 25 - s = 25 - 10 = 15 tickets</span>
<span>Result: There were 15 drakes fan club and 10 no members tickets sold.</span>
