20

Explanation:

Here are the options to this question :

A. 10, 10

B) 25, 5

C) 12; 20

D) 16, 8

If Jane buys 10 units of clothing and 10 units of food : (10 x $25) + (10 x $10) = $350. This doesn't maximise his income

If Jane buys 25 units of clothing and 5 units of food : (25 x $25) + (5 x $10) = $675. This is greater than income

If Jane buys 12 units of clothing and 20 units of food : (12 x $25) + (20 x $10) = $500. This maximises income

If Jane buys 16 units of clothing and 8 units of food : (16 x $25) + (8 x $10) = $480. This doesn't maximise his income
