PLEASE HELP The graduation rate of a local high school is growing at a rate which can be estimated by the following linear model, where y represents the graduation rate, as a percentage, x years after 2017.
y = 74.18 + 1.57x
Use the model to predict the first year in which the school will exceed a 90% graduation rate.

your answer is the frist one

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
