<h3>The equation represents the total amount Emma earns at the event is y = 10x</h3>
<em><u>Solution:</u></em>
Given that,
<em><u>The total amount Emma earns, y, is proportional to the number of bracelets, x, she sells</u></em>
Where,
y is the total amount Emma earns
x is the number of bracelets
k is the cost of each bracelet
<em><u>Emma earns $10 for each sold bracelet</u></em>
Therefore, k = 10
Thus, eqn 1 becomes,
<h3>y = 10x</h3>Thus the equation represents the total amount Emma earns at the event is found
