At a bookstore, the cost for a novel and a magazine is $8.27. The cost for 3 novels and 5 magazines is $20.22. Which pair of equations can be used to determine n, the cost of a novel, and m, the cost of a magazine? n + 5m = 8.27 3n + m = 20.22 n + 5m = 8.27, , 3n + m = 20.22, n + m = 8.27 3n + 5m = 20.22 n + m = 8.27, , 3n + 5m = 20.22, n + m = 20.22 3n + 5m = 8.27 n + m = 20.22, , 3n + 5m = 8.27, 3n + m = 8.27 n + 5m = 20.22

n + m = 8.27; 3n + 5m = 20.22

Step-by-step explanation:

Let

Cost of the novel = n

Cost of the magazine = m

The cost for a novel and a magazine is $8.27.

n + m = 8.27 (1)

The cost for 3 novels and 5 magazines is $20.22

3n + 5m = 20.22 (2)

The pairs of equation to determine n, cost of the novel and m, cost of the magazine is

n + m = 8.27; 3n + 5m = 20.22

Combining (1) and (2)

idk

step-by-step explanation: i just don't

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
