Answer:
14 Striped and 10 Flowered
Step-by-step explanation:
This can best be determined using a set of linear equations that are solved simultaneously.
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations. It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation
Given that the green and blue striped shirt is $15 and the white with purple flowers is $13. She needs to order 24 shirts and has a total of $340 to spend, let the number of striped shirts be g and that of flowered be h then,
g + h = 24 and
15g + 13h = 340
g = 24 - h
15(24 - h) + 13h = 340
360 - 15h + 13h = 340
2h = 20
h = 10
g = 24 - h
g = 24 - 10
= 14
What we know:
- number of meeting rooms = m
- chairs in each meeting room = 325
Since we need an equation to represent the number of chairs in m meeting rooms, we would multiply the amount of chairs per meeting room (325) by m. This amount is c. So the equation becomes:
c = 325m
Now the question asks for the amount of chairs if there are 7 meeting rooms in the hotel. To find this, substitute 7 for m into c = 325m.
c = 325m
c = 325(7)
c = 2275
Answer:
The equation is c = 325m, and the amount of chairs if m equals 7 is 2,275.
Answer:
y = 1 , x = 3
Step-by-step explanation:
3x + y = 10
x = 2y + 1
3(2y + 1) + y = 10
6y + 3 + y = 10
7y = 7
y = 1
x = 2(1) + 1
x = 3
