3) A linear equation to represent this would be 205 = 10x + b
x is days passed, which is 10, and b is the original amount.
10 times 10 is 100, so we now have 205 = 100 + b
Subtract 100 from both sides to get 105 = b, which is the starting amount.
The rate of change is 10, however many cans brought per day.
4) So it appears that for every 5 minutes she frosts 4 cupcakes, which means the rate of change is 4/5 using rise over run.
Subtract 4 from 28 to get the starting amount 5 minutes earlier.
The starting amount of frosted cupcakes is 24.
5) Every 3 months he gets 9 more CDS. So, every month he gets 3 new CDs.
That means the slope is 3.
Subtract 9 from 18 to get the starting amount.
The starting amount of CDs is 9.
Hope this helps!
The number of people attended dinner is 102.
<h3>What is an Equation ?</h3>
An equation is a mathematical statement when two algebraic expressions are equated by an equal sign.
It is given in the question that
An awards dinner costs $225 plus $5 for each person making reservations
the total bill is $735
people attended the dinner = ?
Let x number of people attended the dinner
$225 + $5 * x = $735
5x = 735-225
5x = 510
x = 102
Therefore , 102 people attended the dinner.
