To find the total amount earned, you need to multiply the number of hours worked by the pay rate. Joe worked x hours for 2 days. That’s 2x hours. He worked 8 hours for 2 days. That’s 8(2), or 16 hours. The total number of hours he worked is 2x + 16. He gets paid $9/hour, so an expression for the total amount earned is 9(2x + 16), or 18x + 144.
362/1000 = 181/500
I only know that one, sorry
Notice that 45 hours is 3 times the half-life of 15 hours.
After the first 15 hours, 450 g decays to half this amount, 225 g.
After the next 15 (total 30), 225 g decays to 112.5 g.
After the next 15 (total 45), 112.5 g decays to 56.25 g.
