Step-by-step explanation:
Associative Property of Multiplication is a(bc) = (ab)c
d is the only one that follows the rule
The amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad is $ 390.24.
Given that:-
Price of the laptop after 1 year = $ 400.
Inflation rate = 2.5 %
We have to find the amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad.
Let the price he had to pay be x.
Hence, we can write,
x + (x*(2.5)*1)/100 = 400
x(1 + 1/40) = 400
x(41/40) = 400
x = 400*40/41 = $ 16000/41 = $ 390.24.

I'm not sure if this is the right answer, but here goes nothing. To find the amount of money you would make in one day, you have to multiply 1.10 times 1 penny (because you want to add .10 AND the penny) then you multiply that by 365 for how much you make in a year which is 401.5 then multiply that by 35 years, and you get 14052.5. Sorry if that's wrong! Good luck!
4m+28=44
4m=44-28
4m=16
m=16/4
m=4
