Caf$$ manager, Gary, suspects that demand for latte coffees depends on the price being charged. Based on historical observations, Gary has gathered the following data, which show the numbers of these coffees sold over four different price values:

Price

$$2\mathrm{.}7$

$$3\mathrm{.}6$

$$2\mathrm{.}1$

$$4\mathrm{.}3$

Number of cups sold

$760$

$510$

$990$

$240$

Given that the new price per cup is $$2\mathrm{.}75,$ the forecasted sales for latte coffees will be $\_\_\_\_\_$ cups using Associative model $($linear regression$)($enter your response rounded to one decimal place$).$
