Boa saved $179 a month he saved $145 less than ada each month. how much would ada save in three and a half years

  I think your answer would be $69984. But I'm not 100 percent.

$7.50x+$4.50y=midk it's been awhile since i've done one of these

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
