The two singers will charge the same amount for money at 3.53 hours

Step-by-step explanation:

Let the number of hours be represented by y

Ida needs to hire a singer for her wedding.

Singer A is offering his services for an initial $80 in addition to $13.35 per hour.

= $80 + $13.35(y)

= 80 + 13.35y

Singer B is offering her services for an initial $86 in addition to 11.65 per hour.

= $86 + $11.65 × y

= 86+ 11.65y

When will the two singers charge the same amount for money?

Singer A = Singer B

80 + 13.35y = 86+ 11.65y

Collect like terms

= 13.35y - 11.65y = 86 - 80

1.7y = 6

y = 6/1.7

y = 3.5294117647 hours

Approximately = 3.53 hours

The two singers will charge the same amount for money at 3.53 hours

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
