elena-14-01-66 [18.8K]
Define the two friends as person A and person B.

Let x =  the sales in a week.

Person A:
$125 per week plus 18% commission on sales.
Earnings in a week on x sales is
125 + 0.18x

Person B:
$85 per week plus 21% commission on sales.
Earnings in a week on x sales is
85 + 0.21x

For the two earnings to be equal,
85 + 0.21x = 125 + 0.18x
0.03x = 40
x = 40/0.03 = $1333.33

Answer: $1,333.33

If the rate at which the temperature fell is 4/5 degree/hour then we can simply multiply 5 hours to get our answer.

I hope this helps. If something is confusing or this answer is wrong, don't be afraid to drop me a DM telling me what is wrong.
