Answer:
During the 9th week
Step-by-step explanation:
Scott: 50 + (0.3)(8×25)t
= 50 + 60t
Sophia: 50 + 45t + 30(t-4)
= -70 + 75t
60t + 50 = 75t - 70
15t = 120
t = 8
After 8 weeks they will have the same amount,
Which is during the 9th week
We'll let x represent the weight of Ian's dog.
So we can make the formula Ian's dog (x) + Stephen' dog (5x) = 72
So:
x+5x=72
6x=72
x=12
So ian's dog is 12 pounds, but we're trying to find stephen's dog (5x)
We need to multiply x by 5 so:
5(12)=60
Therefore, Stephen's dog is 60 pounds
