Calculate (ClO^-) in a 6% bleach solution. A 6% bleach solution contains 6 grams of NaClO per 100 grams bleach. The density of 6% bleach is 1.07 g/mL.

1) To calculate Samuel's gross pay, we first need to determine his regular wage for the week. He worked 42 hours at a rate of $7.25/hour, so his regular pay is 42 x $7.25 = $304.50. To calculate his commission, we need to multiply his total sales by his commission rate of 10%, so his commission is $11,000 x 0.1 = $1,100. To calculate his total gross pay, we add his regular pay and commission: $304.50 + $1,100 = $1,404.50. 2) To calculate Charlotte's gross pay, we first need to determine her regular wage for the week. She worked 48 hours at a rate of $9/hour, so her regular pay is 48 x $9 = $432. Next, we need to determine her commission pay. She made 62 sales at a rate of $25/sale, so her commission pay is 62 x $25 = $1,550. To calculate her total gross pay, we add her regular pay and commission: $432 + $1,550 = $1,982. 3) To calculate James's gross pay, we first need to determine his regular wage for the week. He worked 45 hours at a rate of $11.70/hour, so his regular pay is 45 x $11.70 = $526.50. To calculate his commission, we need to multiply his total sales by his commission rate of 12%, so his commission is $7,200 x 0.12 = $864. To calculate his total gross pay, we add his regular pay and commission: $526.50 + $864 = $1,390.50.
