Ответ:
The answer to your question is 1 pink and 4 yellow tulips
Step-by-step explanation:
Data
number of pink tulips and yellow = 5
cost of tulip yellow = y = $2
cost of tulip pink = p = $1
total cost = $9
Process
1.- Write equations to solve this problem
p + y = 5
1p + 2y = 9
Solve by elimination
-1 ( p + y = 5) - p - y = -5
1p + 2y = 9 p + 2y = 9
0 + y = 4
2.- Find p
p + 4 = 5
p = 5 - 4
p = 1
3.- Conclusion
She bought 1 pink tulip and 4 yellow tulips
Ответ:
she bought 1 pink tulip and 4 yellow tulips.
Step-by-step explanation:
Let x represent the number of pink tulips that she bought.
Let y represent the number of yellow tulips that she bought.
Christine bought 5 pink and yellow tulips to make a bouquet. This means that
x + y = 5
The pink tulips cost $1 a piece and the yellow tulips cost $2 a piece. If Christine spent exactly $9 on the tulips, it means that
x + 2y = 9 - - - - - - - - - - -1
Substituting x = 5 - y into equation 1, it becomes
5 - y + 2y = 9
- y + 2y = 9 - 5
y = 4
x = 5 - y = 5 - 4
x = 1
