Question

Q4. Pedro's luncheonette is open six days a week. His income for the first five days was $1,200, $1,200, $2,000, $1,400 and $3,000. How much money must she make on the sixth day to average $2,000 for the six days?

Answer 1

Answer:

$3200

Step-by-step explanation:

sum of income of first five days = 1200+1200+2000+1400+3000 = 8800

now average = 2000 fir six days

let sixth day income be x

so

a/q

(8800 + x)/6 = 2000

Or

8800 + x = 2000×6

or

x = 12000 - 8800 = 3200 (answer)
