<h2><u>Answers and Explanation</u></h2>

<u>(a) Betty’s expression:</u>

Cost of guest = 10 × x + 10 × x + 10 × x

                    = 10x + 10x + 10x

cost of the venue = 80

Total cost =<em> 10x + 10x + 10x + 80</em>

<u>(b) Dawnie’s expression:</u>

Cost of the location  = $80

Number of guests = x + x + x

Cost of all guests = $10(x + x + x)

Total cost = <em> 10(x + x + x) + 80</em>

<u>(c) Joan’s expression:</u>

Cost of the location = 80

Cost of guest = 10 × x + 10 × x + 10 × x

                    = 10x + 10x + 10x

                    = x(10 + 10 + 10)     ⇒  After factoring out x.  

Total cost =<em> x(10 + 10 + 10) + 80</em>
