Answer:

Chlorine tablets cost $54

pH test kit cos $6.6

Explanations:

Given the following parameters

Price of a bucket of chlorine tablets = $90

Price of a pH test kit = $11

Total price of chlorine tablet and test kit = $90 + $11

Total price of chlorine tablet and test kit = $101

If the manager uses a coupon that applies a 40% discount to the total cost of the two items, the amount paid in total will be;


\text{Amount paid in total after discount=\$101 - (40\% of \$101)}

Simplify the result to have;


\begin{gathered} \text{Total cost after discount=\$101-(0.4}*101\text{)} \\ \text{Total cost after discount=\$101-}40.4 \\ \text{Total cost after discount}=\$60.6 \end{gathered}

Get the money paid for each item after discount;

For the bucket of chlorine;


\begin{gathered} \text{Price of Cl after discount}=90-(0.4*90) \\ \text{Price of Cl after discount}=90-36 \\ \text{Price of Cl after discount=\$54} \end{gathered}

For the price of pH test kit;


\begin{gathered} \text{Price of testkit after discount}=\$11-(0.4*11) \\ \text{Price of testkit after discount=11-}4.4 \\ \text{Price of testkit after discount}=\$6.6 \end{gathered}

Hence the price of chlorine tablets is $54 and while the price of the pH test kit is $6.6
