Answer:
45 people are members at the tennis club
Step-by-step explanation:
Let the number of people in the tennis club be denoted as "x".
Since each of them donated $12.45, then total donated = 12.45x
Since they had $50.25 left over after paying the cost of $510 for the ball, then;
12.45x - 510 = 50.25
12.45x = 510 + 50.25
12.45x = 560.25
x = 560.25/12.45
x = 45
Part A: The coefficients (numbers) are 75 and 25, while the variables (letters) are x and y.
Part B: There are two terms, meaning that this expression is a <em>binomial</em>. The two terms are <em>75x</em> & <em>25y</em>
Part C: The term in the expression that shows the total earned from pizzeria is 75x, which, when simplified, will give you the pizzeria term.
hope this helps
