Answer:
x = 6
Step-by-step explanation:
15 more represents “+15”
3 times a number represents “3*x” which is written as “3x”
So fifteen more than 3 times a number is 33 would be written as;
3x + 15 = 33
Now solve for x using algebra;
3x = 33 - 15
3x = 18
x = 18 / 3
<u>x = 6</u>

Answer:
25x + 15800
Step-by-step explanation:
Given
The amount of money in both banks over time represented by the functions;
f ( x ) = 50 x + 6500 and g( x ) = − 25 x + 9300
The total amount of money in the two accounts over time is expressed as;
h(x)= f(x) + g(x)
Substitute;
h(x) = 50 x + 6500 + (− 25 x + 9300)
h(x) = 50x - 25x +6500+9300
h(x) =25x + 15800
Hence the sum of the money in the account over time is 25x + 15800
Answer:
time period (t) is 2.25 years
Step-by-step explanation:
Given data in question
amount (a) = $94000
principal (p) = $78870
rate (r) = 7.8 % = 0.078
to find out
time period (t)
solution
we know that continuous compound interest formula i.e.
amount = principal 
...............1
we will put all value a, p and r in equation 1
amount = principal
94000 = 78870 
= 94000 / 78870
now we take ln both side
ln ln (94000 / 78870)
0.078 t = ln 1.19183466
0.078 t = 0.175494
t = 0.175494 /0.078
t = 2.249923
so time period (t) is 2.25 years
