Answer:
a
Step-by-step explanation:
This is a formula if you need one. DON'T forget to cross-multiply
3/4 = x/12
Answer:
Part A: x0.50 + 3 = 18.50
Part B: x0.75 + 3 - x0.10 = 21
Part C: The equations from Part A and Part B differ because of the cost of plastic cup.
Step-by-step explanation:
Let x represent the number of cup of lemonade sold. Therefore, we have:
Part A:
This situation can be represented by the following equation:
x0.50 + 3 = 18.50
Part B:
This situation can be represented by the following equation:
x0.75 + 3 - x0.10 = 21
Part C:
The equations from Part A and Part B differ because of the cost of plastic cup.
For equation from Part A, revenue is the same as profit as Sydney does incur any cost to buy plastic cup before selling her lemonade.
For equation from Part B, revenue is different from profit because Daria has to incur the cost of plastic cup which $0.10 per cup of lemonade before selling her lemonade.
Answer:
Jill make $18 on Wednesday
Step-by-step explanation:
Given :Jill is selling lemonade for $1.50 per cup on Tuesday.
To Find :On Wednesday she is selling the lemonade for the same price and sells 12 cups. How much money did she make on Wednesday?
Solution:
Jill is selling lemonade for $1.50 per cup on Tuesday.
Cost of 1 cup of lemonade = $1.5
Cost of 12 cups of lemonade = 
Hence She make $18 on Wednesday
(3p)(3p) or 3p x 3p. Cause the exponent means 3p times 3p
