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

Answer:<BOC= 47
Step-by-step explanation:
Haley’s Percentage Decrease from Test 1 to Test 2 to the nearest tenth is 7.5%
Nearest tenth can be defined as , Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5
Given that,
Haley’s Percent score in Test 1 = 93 %
Haley’s Percent score in Test 2 = 86%
Formula For calculating the Percentage Decrease is :
(Beginning Percentage – Final Percentage) / Beginning Percentage * 100
So, by using this formula we can calculate the percentage decrease of Haley’s Test
Percentage Decrease = (93% - 86%)/93% * 100
= 7.5%
