Answer:
Linear function
Step-by-step explanation:
Given
Required
Linear or Exponential
A linear equation has the form: 
;
An exponential has the form: 
By comparing both functions to:
The linear function is similar to
<em>Hence, the given function is a linear function.</em>
Algebra is Faster And Better Than “Basic” Math
Just as multiplying two by twelve is faster than counting to 24 or adding 2 twelve times, algebra helps us solve problems more quickly and easily than we could otherwise. Algebra also opens up whole new areas of life problems, such as graphing curves that cannot be solved with only foundational math skills.
0.9030 > 0.8736
0.9 > 0.8
so your first option is correct
35+5(4-s)=2550
35+20-5s=2550
55-5s=2550
-55 -55
-5s = 2495
s = - 499
-499 + a = 4
+499 +499
a = 503
