(a) of 3000 she makes 55 an hour (h) and how many hours will it take to have an account balance of 3220
a: a=3000+55h;3220
b: 3000+55h =a:5h
c: 55+3000h= a=4hours
d:a=3000 +55h;4hour
From your data, none of those.
3000 + 55h = 3220
i got this question off a benchmark
To find the number of hours it will take to have an account balance of 3220, we can use the given equation: a = 3000 + 55h.
Option A: a = 3000 + 55h = 3220
To solve for h, we isolate the h variable by subtracting 3000 from both sides:
55h = 3220 - 3000
55h = 220
Now, divide both sides of the equation by 55:
h = 220 / 55
h = 4
Therefore, it will take 4 hours to have an account balance of 3220.
The correct answer is option D: a = 3000 + 55h; 4 hours.
