If you just need an answer and are not required to use formal algebra, use logical reasoning.

400 loaves of oatmeal bread would sell for $600; 400 loaves of wheat bread would sell for $800.

The actual sales total of $700 is exactly halfway between $600 and $800; that means half of the 400 loaves were of each type.
