damaskus [11]

Answer:

Alyssa had scored 3 goals today.

Step-by-step explanation:

Given:

Number of goals scored yesterday = $x$

Total number of goals scored in 2 games = 4

We need to find the number of goals scored today.

Solution:

Now Given:

Today she scored 3 times as many goals than yesterday.

So we can say that;

Number of goals scored today = $3x$

Now we know that;

Total number of goals scored in 2 games is the sum of Number of goals scored yesterday and Number of goals scored today.

framing in equation form we get;

$x+3x=4\\\\4x=4$

Dividing both side by 4 we get;

$\frac{4x}{4} =\frac{4}{4}\\\\x=1$

Number of goals scored yesterday = 1

Number of goals scored today = $3x = 3\times1 =3$

Hence Alyssa had scored 3 goals today.

A) Let x = number of presale tickets
y = number of day of show tickets 

x + y =< 800 
6x + 9y >= 5000 

b) 6x + 9y >=5000 
6(440) + 9y >=5000 

y >= 262.2 
263 tickets 

440 advance purchase tickets added to 263 day of show tickets is 703 tickets, which is below the 800 ticket maximum.
