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

### Instruction:
 Jared alihesabu magari 15% chini ya dada yake Ann walipokuwa wakitazama barabarani kutoka shuleni, na Ann alihesabu magari 7 zaidi ya rafiki yao Alfred. Ikiwa Jared alihesabu magari 300, magari yote waliyohesabu ni mangapi?


### Response:
 Ikiwa Jared alihesabu magari 300, na Ann alihesabu 15% zaidi, basi Ann alihesabu 1.15 * 300 = 345 magari.
Jumla ya magari waliyohesabu Ann na Jared ni magari 345 + 300 = <<345+300=645>>645
Ikiwa Ann alihesabu magari 7 zaidi ya rafiki yao Alfred, basi Alfred alihesabu magari 345 - 7 = <<345-7=338>>338
Jumla ya magari waliyohesabu wote ni magari 645 + 338 = <<645+338=983>>983
