Tiffany makes scarves and sells them at a neighborhoodclothing store. The owner charges her $25 a day for thespace she uses. She sells each scarf for $30. Each scarfcosts her $14 to make. How many scarves must Tiffanysell per day to make a profit of at least $100 per day?Write and solve an inequality.

8

Step-by-step explanation:

100 ≥ (30 - 14)x - 25

100 ≥ 16x - 25

100 + 25 ≥ 16x

125 ≥ 16x

x ≥ 7.81

Since a scarf sale can not be a fraction, she must sell at least 8 scarves daily.

11

step-by-step explanation:

32.50-7.50=25

225/25=11

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
