Answer: she bought 13 petunias
Step-by-step explanation:
Let x represent the number of Petunias pot of flowers that she bought.
Let y represent the number of begonias pot of flowers that she bought.
She bought 22 potted plants. This means that
x + y = 22
Petunias cost $7 per pot and begonias cost $8 per pot. She spent a total of $163. This means that
7x + 8y = 163 - - - - - - - - - - - -1
Substituting x = 22 - y into equation 1, it becomes
7(22 - y) + 8y = 163
154 - 7y + 8y = 163
- 7y + 8y = 163 - 154
y = 9
x = 22 - y = 22 - 9
x = 13

Answer:
The ice cream maker should mix 210 gallons of ice cream with 4% butterfat and 90 gallons of the ice cream with 14% butterfat.
Step-by-step explanation:
We are given the following in the question:
We want the mixture with 7% butterfat.
Amount of mixture = 300 gallons
Amount of butterfat in mixture =
Let x gallons of 4% butterfat used in mixture.
Butterfat in x gallons =
Amount of 14% butterfat used in mixture =
Butterfat in (300-x) gallons =
Thus, we can write the equation:
Butterfat in mixture =
Thus, the ice cream maker should mix 210 gallons of ice cream with 4% butterfat and 90 gallons of the ice cream with 14% butterfat.
