Answer:
a) 7 weeks b) George's
Step-by-step explanation:
Sally's score can be modeled by 10x+850.
George's score can be modeled by 50x+570.
We can set them equal to each other to see when they intersect.
10x+850=50x+570
40x=280
x=7
If George overtakes her in the 7th week, of course he'll have the higher score in 12 weeks.

Answer:
$6.43
Step-by-step explanation:
You start by multiplying $1.49 by 5 because you bought 5 cartons for $1.49, that would equal $7.45. Then, you multiply $3.06 by 2 because you bought 2 gallons, and you will get $6.12. Then you add both answers: $7.45 and $6.12. And you will get $13.57. Then, you hand him a $20, so $20 minus $13.57 equals $6.43! Please mark as brainliest! I worked hard! Plus hope this helps =)
