The total cost in dollars, T, of new aluminum ladders at a home improvement store is
estimated by multiplying the length of the
ladder in feet, f, by 4.5 and then adding $15.00.
1. Which equation matches the above
information?
a. T= 4.5 f + 15
b. f= 4.5 T + 15
C. T= 15 f +4.5
d. f= 15 T +4.5

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.
