The losing candidate in a mayoral election received 10,200 votes, which represented 30% of all votes cast in the election.
ElenaW [278]

well, in the election, the losing candidate received 10200 votes, and we know that's 30% of the whole votes cast, le's say the whole amount is "x" or namely 100%.

B)

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 10200&30\\ x&100 \end{array}\implies \cfrac{10200}{x}=\cfrac{30}{100}\implies \cfrac{10200}{x}=\cfrac{3}{10} \\\\\\ 102000=3x\implies \cfrac{102000}{3}=x\implies 34000=x

A)

Dorian's 3060 is really 30% of 10200, however, the losing candidate received 30% of the total votes cast, and that is 10200, so Dorian mistakenly is using 30% of the 30% received by the losing candidate as point of reference for her total.

Write an expression to represent four more than the problem of three and a number z
kicyunya [14]

Answer:

If the "problem of 3 and a number z" is multiplying: 4+(3z)

If it's about adding: 4+(3+z)

Step-by-step explanation:

Scenario A: If it's 3 and z, then that means it's 3z, and we're adding 4, so it's 4+(3z) (make sure to put () around the 3z!)

Scenario B: If 3 and z is also 3+z, then the equation is 4+(3+z) (also use () on this too!)
