Gina chuez has considered starting her own custom greeting card business. with an initial start up cost of $1500, she figures it will cost $0.45 to produce each card. in order to remain competitive with the larger greeting card companies, gina must sell her cards for no more than $1.70 each. to make a profit, her income must exceed her costs. how many cards must she sell before making a profit?
a. 1187 b. 1230 c.1200 d.1425

1.70 - 0.45 = 1.25

1500 ÷ 1.25 = 1200

Gina must sell 1200 cards before she can make a profit

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
