To do this,find anything like you mentioned that has a survey. Now a survey must use ratios to get conclusion because you must first figure out how many people out of the entire group are divided to get an answer. Lets say you take a survey over ice cream. You survevy 40 people. 25 people vote vanilla,10 vote chocolate,and 5 vote strawberry. You would use these ideas to conclude that most people like vanilla and not very many people like strawberry. Hope this makes sense :)

Original price $60 markup 15%
Ivenika [448]

When you mark up a price, multiply the original price by 1 plus the amount of the mark up as a decimal.

15% = 0.15 + 1 = 1.15

$60 x 1.15 = $69

Its a word problem in algebra 1 that i need help on step by step ?
Luden [163]

Answer:

Cost of one rose bush =  $2 and cost of 1 geranium = $11

Step-by-step explanation:

lets assume cost of one rose bush = $x

lets assume cost of one geranium = $y

Given that Norachai spent $13 on 1 rose and 1 geranium

⇒ 1 × (cost of one rose bush) + 1× (cost of one geranium) = 13

⇒ 1x + 1y = 13     ----------------------------equation 1

Also given that Castel spent $46 on 1 rose bush and 4 geraniums

⇒1 × (cost of one rose bush) + 4× (cost of one geranium) = 46

⇒ 1x + 4y = 46    ----------------------------equation 2

Now we are having following two equations which will be used to find the value of x and y

1x + 1y = 13     ----------------------------equation 1

1x + 4y = 46    ----------------------------equation 2

lets modify equation 1 to get value of  y in terms of x and name that equation as equation 3

1x + 1y = 13     ----------------------------equation 1

⇒ y = 13 - x    -----------------------------equation 3

On substituting value of y from equation 3 in equation 2 we get

1x + 4 × ( 13 - x ) = 46

⇒ x + 52-4x =46

⇒ -3x = 46-52

⇒     x = (-6)/(-3) = 2

on substituting calculated value of x that is 2 in equation 3 we get

y = 13 -2 = 11

so on solving the equations we get x = 2 and y = 11.

Hence cost of 1 rose bush = $x = $2 and cost of 1 geranium = $y = $11
