One troop member So tickets for 33 crab meals and 20 vegetarian meals with a total receipt of $2025 another sold tickets for 30

natima [27]

Answer:

Therefore the cost of a crab meal and a vegetarian are $40.41 and $1.94 respectively.

Step-by-step explanation:

Given that,tickets for 33 crab meals and 20 vegetarian meal with total receipt of $2025. Another sold ticket for 30 crab meal and 11 vegetarian meals with total receipt of $1827.

Let the cost of a crab meal and a vegetarian meal be x and y respectively.

The cost of a crab meal is x

The cost of 33 crab meal is $33x

The cost of 30 crab meal is $30x

The cost of a vegetarian meal is y.

The cost of 20 vegetarian meal is $20y.

The cost of 11 vegetarian meal is $11y

According to problem,

33x+20y=2025

33x+20y-2025=0........(1)

and

30x+11y=1827

30x+11y-1827=0 ..........(2)

Cross Multiplication Method,

$a_1x+b_1y+c_1=0$

$a_2x+b_2y+c_2=0$

$\frac{x}{b_1c_2-b_2c_2}=\frac{y}{a_2c_1-a_1c_2}=\frac{1}{a_1b_2-a_2b_1}$

${x}=\frac{b_1c_2-b_2c_2}{a_1b_2-a_2b_1}$

${y}=\frac{a_2c_1-a_1c_2}{a_1b_2-a_2b_1}$

Here $a_1=33$ , $b_1=20$ , $c_1=-2025$ , $a_2=30$ , $b_2=11$ , $c_2=-1827$

$\therefore x=\frac{20.(-1827)-11.(-2025)}{33.11-30.20}$ $y=\frac{30.(-2025)-33.(-1827)}{33.11-30.20}$

$\approx 40.41$ $\approx 1.94$

Therefore the cost of a crab meal and a vegetarian are $40.41 and $1.94 respectively.

Mrs. Paige gave her daughter, Megan, $700 to open a savings account. Each month, Mrs. Paige gives Megan $25 to deposit into her

Firdavs [7]

Answer:

700 + 25m = 1000 is the correct equation

Step-by-step explanation:

In this question, we are tasked with finding the equation that represents the number of months m which in which megan will have $1000 in her account.

Now for her daughter, there are two kinds of ways she generates money for he account. The $700 see money her mother gave her and the $25 she has per month.

Thus after m months, the total she would have raised from the $25 each would be $25m

Now, we add this to the $700 see money and equate to $1000

Mathematically we have;

700 + 25m = 1,000
