[quiet dome]

which question do u need help with

the first one, your multiplying 2.5 by 6

then subtracting from 75

to get you back to the initial weight of the lift

[quiet dome]

for the second one you could expand all three brackets but thats a little bit long, so you could either use pascals triangle, or use the Combination function on your calculator and you should get your answer for that

for the third one, your INCREASING your initial amount of money by 8% (assuming that the interest is applied monthly as it isnt stated in the question), so your decimal multiplier will be 1.08, which ur multipllying by itself 9 times.

so u would do 6500*1.08^9

and that wouldnt be ur FINAL answer
