Proportion: $1 coupon / 3 salads = $10 in coupons / x salads
Solving proportion:
1/3 = 10/x
30 = x
x = 30 salads
You would need to buy 30 salads to get $10 in coupons.
Hope this helps!! :)

Proving a statement by contrapositive means that if you want to prove that , you can instead prove that since the two are equivalent.
So, proving that by contrapositive means to prove that
since of course the negation of being odd is being even.
This claim is quite easy to prove: if n is even, then it is twice some other integer k:
This means that its square is
And so, if n is even, its square is also even. This proves, by contrapositive, that if n squared is odd, then n is odd.
Acceleration is:
a=g
Velocity is the integral of the above
v=gt+v0
And position is the integral of the above
h=gt^2/2+v0t+h0
You are given that v0=15ft/s and h0=0ft and let g≈-32 so
h(t)=-16t^2+15t
It will hit the ground when h(t)=0 so:
0=-16t^2+15t which is equal to
16t^2-15t=0 factor
t(16t-15)=0, since we are looking for the time other than zero...
t=15/16 of a second :)
So they obviously just rounded to one whole second. So C.) was the correct answer. (Although I would say they are all wrong because they didn't SAY to round the answer :P) Haha, not trying to confuse you, the answer is most likely C. because they had the correct equation.
