Miles has saved $40. he wants to buy a cell phone for $129 in about 4 months. to find out how much he should save each week, he wrote 40 + 16x = 129. is his equation accurate? why or why not?

Heptagon is the correct ans

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.
