Answer:

He made an error of 0.69%

Step-by-step explanation:

Step one:

Diep savings

time= 12 months

expected savings= $1450

Step two:

let us solve for the amount he needs to save per month.

we do this by dividing the expected savings by 12

1450/12=$120.83

error= actual -expected/expected

error= 120.833-120/120

error=0.833/120

error=0.0069*100

error=0.69%
