Savings Application Devin has $100 in savings and is planning to add $50 each week. Laura has $400 in savings
and is planning to add $40 each week. Their plan is to wait until their savings are equal
and then load up their old Volkswagen bus and take a road trip. They figure out that the
equation used to determine how many weeks it will take until their savings are equal is
50w + 100 = 40w + 400, where w is the number of weeks they have been saving.
How many weeks will Devin and Laura have to continue to save until they both have the
same amount in savings and they can go on their road trip?
Devin and Laura will have the same amount in savings after
weeks

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 correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
