Answer:
Here's exactly what I would write:
a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies, d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies
a = 4d
b = 3e
c = 2f
Expression for Sandy: 4d + 3e + 2f
Expression for Sandy and Nina: 5d + 4e + 2f
Step-by-step explanation:
This is a terrible question that makes people feel frustrated. I'm sorry.
a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies,
d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies
Sandy has 4 times the number of cupcakes as Nina: a = 4d
Sandy has 3 times the number of gummy bears as Nina: b = 3e
Sandy has 2 times the number of brownies as Nina: c = 2f
An expression for how many desserts Sandy is bringing: a + b + c
An expression that could be used for how many desserts Sandy and Nina are bringing together: a + b + c + d + e + f, but I think they want you to substitute the equivalent values like above (a = 4d)
Sandy: 4d + 3e + 2f
Sandy and Nina: 5d + 4e + 2f
because 4d + 3e + 2f + d + e + f = 5d + 4e + 2f
I'm sorry I don't have a simpler way to explain this. It's a painful question. I will answer any questions you have.
