### Instruction:
 Caleb na Cynthia wanajaza bwawa lao la kujazia maji kwa kutumia ndoo. Wanajaza ndoo zao kwenye bomba na kuzibeba hadi kwenye bwawa. Caleb anaweza kuongeza galoni 7 kutoka kwenye ndoo yake na Cynthia anaweza kuongeza galoni 8 kutoka kwenye ndoo yake kila safari. Itachukua galoni 105 kujaza bwawa. Itawachukua safari ngapi Caleb na Cynthia kujaza bwawa kwa kutumia ndoo zao?


### Response:
 Kila safari, wataongeza galoni 7 za Caleb + galoni 8 za Cynthia = <<7+8=15>>15 galoni.
Caleb na Cynthia watatakiwa kufanya jumla ya galoni 105 / 15 galoni kwa safari = <<105/15=7>>7 safari.
