Answer:
85 and -31
step-by-step:
x + y = 54
x - y = 116
solve for x in first equation
x = 54 - y
sub into second equation
54 - y - y = 116
54 - 2y = 116
-2y = 62
y = -31
sub in x equation
x = 54 - (-31)
x = 85
Answer:
After 5 years, savings account = $241.00
After 8 years, savings account = $269.53
Step-by-step explanation:
If the savings account increases by 3.8% per year, this means it will be 103.8% of the previous year's value since 100% + 3.8% = 103.8%
103.8% in decimal form = 103.8/100 = 1.038
Therefore, the exponential function is:
, where
is the number of years
So when
,

After 5 years, savings account = $241.00
After 8 years, savings account = $269.53
