Step-by-step explanation:
I searched it up.
Option 1: $50
Option 2: $12.50 per hour.
50 ÷ 12.50 = 4
Paul can choose the hourly wage if he works more than 4 hours.

12.50 x 5 hours = 62.50
$62.50 is higher than the fixed rate of $50. Thus, hourly wage is the better option.

April worked 1 1/2 times as long as Carl did. 1 1/2 can be rewritten as 3/2. Number of Hours April worked on math project 3/2 times the Number of Hours Carl worked on Math project. Which Carl worked 5 1/4 hours long, which can be rewritten as 21/4
Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
= 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
= 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.
So it can be said that Marcia made a more concentrated salt solution.
