1) Solve for Valerie’s weight for in 0 weeks
Since it’s zero you rid of the t and get 235
Now Oscar’s weight in week 0 is 247. Which means Oscar weights more.
2) Solve for Oscar’s multiplier. 247 - 243 = 5 now divide by 2 because he weighs 243 in the second week. So his slope is -2.5 cause it’s decreasing. Valerie’s multiplier is the same. So they are losing weight in around the same rate.
3) you already have Valerie’s equation. Now solve for Oscar’s. You actually already have because you did the 2 previous problems. We know his multiplier is -2.5 and he weights 247 in the beginning so arrange it like Valerie’s equation.
W = 247 -2.5t
