60 flowers. She usually buys 12 flowers, and there is a 20% discount, so 20%=1/5, so 12*5=60

Saniyah Mcneil · Answer 2

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
