Sarah works as a waiter. she earns $80 each weekend plus 15% in tips. this weekend, sarah earned $252.50 in all. what is the dollar amount of the meals that sarah served?

The dollar amount of the meals Sarah served was $1150.

Step-by-step explanation:

Set up an equation expressing Sarah's total earnings:

(total earned) = (base wage) + 0.15 * (price of meals served)

Now the same using what we know:

$252.50 = $80 + 0.15 * x

where x is unknown and can be solved for:

x = (252.50 - 80) / 0.15 = $1150

The dollar amount of the meals Sarah served was $1150.

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

the answer should be a. snail
