Answer:
Barbara paid total amount of $339.94 before taxes.
Step-by-step explanation:
As tax amount or percentage is not give, we can assume that the sum of all the items is the total cost Barbara paid.
We will add up all the costs.
Entry fee = $18
And separate fee of $7.50 per week for 16 weeks, total amount is =
Cost of bowling ball = $102
Cost of a bag = $39.95
Cost of glove = $11.00
Cost of a pair of shoes = $48.99.
Adding up all values =
=$339.94
Thus, we can say that Barbara paid a total amount of $339.94 before taxes.

<em><u>The system of linear inequalities are:</u></em>
<em><u>Solution:</u></em>
Let "a" be the number of small candles bought
Let "b" be the number of large candles bought
<em><u>He needs to buy at least 20 candles</u></em>
Therefore, number of small candles and number of large candles bought must be at least 20
Thus, we frame a inequality as:
"at least" means greater than or equal to
Here, we used "greater or equal to" symbol because, he can buy 20 candles or more than 20 candles also
From given,
Cost of 1 small candle = $ 2.50
Cost of 1 large candle = $ 7
<em><u>He can spend no more than 80 dollars</u></em>
Which means, he spend maximum 80 dollars or less than 80 dollars also
So we have to use "less than or equal to" symbol
<em><u>Thus, we frame a inequality as:</u></em>
Number of small candles bought x Cost of 1 small candle + number of large candles bought x Cost of 1 large candle 80
<em><u>Thus the system of linear inequalities are:</u></em>
