Students at a bake sale sell bags of cookies for $2.35 each and bags of miniature muffins for $1.75 each. while selling their baked goods, the students also received a $20 donation. the amount of money the students make from selling c bags of cookies and m bags of muffins can be modeled by the expression 2.35c + 1.75m + 20. interpret the expression 2.35c + 1.75m in this context.
a
the expression 2.35c + 1.75m represents the money earned from selling c bags of cookies.
b
the expression 2.35c + 1.75m represents the money earned from selling m bags of muffins.
c
the expression 2.35c + 1.75m represents the money earned from selling c bags of cookies and m bags of muffins.
d
the expression 2.35c + 1.75m represents the money earned from selling one bag of cookies and one bag of muffins.

Option C (The expression 2.35c + 1.75m represents the money earned from selling c bags of cookies and m bags of muffins).

Step-by-step explanation:

It is given that a bag of cookies is priced at $2.35 and a bag of muffin is priced at $1.75. It is also given that the student sells c bags of cookies and m bags of muffins. The total revenue earned by the student by selling c bag of cookies = $2.35 * c bags = $2.35c and the total revenue earned by the student by selling m bag of muffins = $1.75 * m bags = $1.75m. Therefore, the total revenue earned by the student by selling both cookies and muffins = 2.35c + 1.75m. This expression (2.35c + 1.75m) represents the money earned from selling c bags of cookies and m bags of muffins. Therefore, C is the correct choice!!!

c is the answer

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
