7 0

Since Carmen gives two coins to Frankie for every five that she gets, she effectively only gains 3 coins at a time. Therefore, if she has 9 coins, Frankie must have 6.

Mark earns $135 for selling a $1,500 refrigerator. Which sale listed has the same commission rate? A) $36 commission on a $400 d

sdas [7]

So the percentage Mark makes comparative to the price of the refrigerator sold is $\frac{135}{1500}=0.09=$ 9%. If we take 9% of the given sale prices:
A: $0.09*400=36$
B: $0.09*500=45$
C: $0.09*1400=126$
D: $0.09*600=54$

So (A) has the same commission rate.

Marat540 [252]

Answer:

$\frac{4}{5}$

Step-by-step explanation:

$\frac{ - 14}{5} + x = - 2 \\ x = - 2 + \frac{14}{5 } \\ x = \frac{ - 10 + 14}{5} \\ \: x = \frac{4}{5} \\ therefore \: the \: other \: number \: is \: \frac{4}{5}$
