$\large{ \tt{ - \: HEY \: AH~\:♡ }}$

$\large{ \tt{✺ \: SOLUTION}} :$

Provided : Total sold bakery items : 3028 coffee buns and blueberry buns & 1560 more coffee buns were sold than the blueberry buns.

To find : Number of coffee buns the bakery sold

- First , Subtract 1560 from 3028 :

$\large{ \tt{→ \: 3028 - 1560 = 1468}}$

We just subtacted the number of more coffee buns from the number of told items sold which means that the number of coffee buns and the number of blueberry buns sold are equal for now. Now divide 1428 by 2 :

$\large{ \tt{→ \frac{1428}{2} = 734 }}$
