Hi There!
The hot coca mad by Eli is more chocolaty because it has more chocolate in lesser amount of water.
Because, Arjun takes quantity of chocolate = 20 mL
Choice 1.
Arjun takes quantity of water = 33 ounces
The Chocolate to Water ratio is
Chocolate : Water = 20 : 33
Dividing by 20, We get
Chocolate : Water = 1 : 1.65
Choice 2.
Arjun add 1 ml of chocolate in 1.65 ounces of water.
Eli takes quantity of chocolate = 45 mL
Eli takes quantity of water = 66 ounces
The Chocolate to Water ratio is
Chocolate : Water = 45 : 66
Dividing by 45 , we get
Chocolate : Water = 1 : 1.47
Eli add 1 ml of chocolate in 1.47 ounces of water.
So, The hot coca mad by Eli is more chocolaty because it has more chocolate in lesser amount of water.
Good Luck!

Option C -![128 + 8.50x + 9.50y + 10z](/tpl/images/0475/6179/99aa4.png)
Step-by-step explanation:
Given : The Jones family plans a trip to the amusement park a purchase a family package for $128.00. They also want to buy lunch and souvenir cups. The chicken platter costs $8.50 each and the burger platter costs $9.50 each. The souvenir cups each cost $10.00
To find : Which of the following algebraic expressions can be used to describe the amount of money the Jones family will spend, before sales tax, based on the number of each meal and souvenir cups purchased?
Solution :
Let x represent the number of chicken platters.
Let y represents the number of burger platters.
Let z represent the number of souvenir cups.
A family package cost is $128.00.
The chicken platter costs $8.50 each
The cost of x chicken platter =![8.50x](/tpl/images/0475/6179/130f7.png)
The burger platter costs $9.50 each.
The cost of y burger platter =![9.50y](/tpl/images/0475/6179/ec084.png)
The souvenir cups each cost $10.00
The cost of z souvenir cups =![10z](/tpl/images/0475/6179/45e11.png)
Therefore, Total they spend is![128 + 8.50x + 9.50y + 10z](/tpl/images/0475/6179/99aa4.png)
Hence, Option C is correct.
