Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Heather is going to sew 150 aprons that are to be used for a kiddie crew program. She already was able to sew  13 aprons, and today, she sewed three times as many aprons. How many aprons should she sew tomorrow if she wants to sew half of the remaining number of aprons needed?

### Response:
 Heather anahitaji kushona jumla ya mapochi 150 mapochi - 13 mapochi = <<150-13=137>>137 mapochi.
Heather ameshona mapochi 13 x 3 = <<13*3=39>>39 leo.
Hivyo, bado kuna mapochi 137 mapochi - 39 mapochi = <<137-39=98>>98 ya kushonwa.
Heather anahitaji kushona mapochi 98 mapochi/2 = <<98/2=49>>49 mapochi.
