Respuesta :

Answer:

180- 172 =8 $ 8/3 =2.56


Step-by-step explanation:

Answer: The linear equation to represents the total in the checking account :

f(x) = $180-$2.5x

Step-by-step explanation:

Since we have given that

Amount showing at the beginning of the month = $180

After 3 days,

Balance shown in checking balance  = $172.50

So, difference in 3 days would be

[tex]\dfrac{180-172.5}{3}\\\\=\dfrac{7.5}{3}\\\\=\$2.5[/tex]

Hence, the linear equation to represents the total in the checking account :

f(x) = $180-$2.5x
