What the person above me said ⬆️
Answer:
Alice is 47 pounds havier than Jamie.
Step-by-step explanation:
Let be "j" the weight in pounds of Jamie, "l" the weight in pounds of Lily and "a" the weight in pounds of Alice.
Based on the data given in the exercise, we can know that:
[Equation 1]
[Equation 2]
[Equation 3]
Solve "j" from the Equation 2:
Substitute this equatio and the Equation 3 into the Equation 1 and solve for "l":
Substitute the value of "l" into the equation to find "j":
Substitute the value of "l" into the Equation 3 to find "a":
Subtract the weight of Jamie from the weight of Alice in order to find how much heavier is Alice than Jamie:
Alice is 47 pounds havier than Jamie.
If you graph the equation then one of the point should be on (5,1)
Well the answer would be 25% decrease.
hope that helped
