### Instruction:
Patricia is growing her long very long to donate it to a charity that makes wigs for cancer survivors. Her hair is 14 inches long. She needs to donate 23 inches to make a wig. She wants her hair to be 12 inches long after the donation. How much longer does she have to grow her hair?

### Response:
 Nywele zake zinahitaji kuwa na urefu wa inchi 35 anapozikata kwa sababu 32 + 3 = <<32+3=35>>35
Anahitaji kuongeza urefu wa inchi 21 kwa sababu 35 - 14 = <<35-14=21>>21
