Arianna is buying plants for her garden. She buys 15 flowering plants for $96. Pink flowering plants sell for $8, and purple flowering plants sell for $5. How many pink flowering plants did Arianna buy?

x+y=15

8x+5y=96

now just solve for x and y

A cell phone store sells the basic model of a phone for $30 and the upgraded model for $100 when a customer signs a two-year agreement. On Tuesday, the store has $900 in sales. The store pays $5 for each basic model and $25 for each upgraded model. If the cost of the cell phones sold on Tuesday is $200, how many upgraded models were sold?

7 pink plants for $56 and 8 purple flowers or $40

everyone is so negative on this sight

To find out how many pink flowering plants Arianna bought, we can set up a system of equations based on the given information.

Let's assume Arianna bought x pink flowering plants.

Since pink flowering plants cost $8 each, the cost of x pink flowering plants would be 8x dollars.

We also know that Arianna bought a total of 15 flowering plants for $96.

So, the number of purple flowering plants she bought would be 15 - x.

Since purple flowering plants cost $5 each, the cost of (15 - x) purple flowering plants would be 5(15 - x) dollars.

We can now set up an equation based on the total cost of the plants:

8x + 5(15 - x) = 96

Simplifying this equation, we have:

8x + 75 - 5x = 96
3x + 75 = 96
3x = 96 - 75
3x = 21
x = 21/3
x = 7

Therefore, Arianna bought 7 pink flowering plants.
