Write an equation to present her daily earnings?

Let daily sales be represented by x and daily earnings be represented by y.

y is calculated as thus;

$y = Earnings + Commission * Sales$

$y = 30 + 2\% * x$

Convert percentage to decimal

$y = 30 + 0.02 * x$

$y = 30 + 0.02x$

Hence, her daily earnings is $y = 30 + 0.02x$
