Answer:
3(x+7) = 3x +21
Step-by-step explanation:
Make a proportion to find the cost for 12 flowers based on the price for 4 flowers.
4/10=12/x
Cross multiply and you get 4x=120 Divide 4 on both sides of the equation.
X is $30.
Then, you find the unit price of 1 flower by dividing 10 by 4. Each flower cost $2.50.
Convert 20% to decimal which is 0.2.
Multiply 0.2 by 2.5 and you get 0.5. Subtract 0.5 from 2.5 to get 2.
Write an equation using the information: $2 for each flower and you only have $30 to spend.
The equation is 2x=30. Divide 2 on both sides and you get x=15 flowers
