Answer: Lottie saved 330 pounds.
Step-by-step explanation:
Lottie's amount can be represented by the expression x + 76 and Kai's amount is unknown so we will also represent by x.
We know that the combination of their savings will be 584 pounds so we will add the expression and set them equal 584.
x + (x + 76) = 584 Now solve for x
2x + 76 = 584
-76 -76
2x = 508
x= 254
If x was Kai's amount then Kai save 254 pounds.
Lottie saved 76 more that Kai
254 + 76 = 330
Lottie also save 330 pounds
