Martina invested her savings in two investment funds. the $12,000 that she invested in fund a returned a 5% profit. the amount that she invested in fund b returned a 1% profit. how much did she invest in fund b, if both funds together returned a 4% profit?

we know she invested 12000 in A, and say "b" dollars in B, so the total amount invested or principal must be 12000 + b.

we also know that those profits added together, yielded only 4% of the total amount invested, namely 4% of (12000 + b), which will be 0.04(12000 + b).

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
