If he earns a flat rate of $400, then he needs to make $350 on commission in order to make at least $750.

Find out what number $350 is 8% of, since he makes 8% commission on sales.

In the percent formula:
a = pb
a is the part, p is the percent (as a decimal), b is the base

350 is 8% of what number?
350 = 0.08b {substituted given values into percent formula and changed 8% to a decimal}
b = $4,375 {divided each side by 0.08}

He needs to make at least $4375 worth of sales.
