Thomas works as a salesperson on Saturday and Sunday at the verizon store he is payed 46.50 each day and for every smart phone h

Triss [41]

So he is paid 46.5 flat every day
he earns 5% of each smart phone he sells
at the time of the problem, smart phones sell for 70 so he earns 5% or 70 or 5/100 of 70 or 1/20 of 70 or 70/20 or 7/2 or 3 and 1/2 or $3.50 per phone he sells

so pay must be at lease 150 so
pay=46.5+ (# of phones times 3.50)
150<46.50+(number of pones times 3.50)
solve for number of phones
subtract 46.5 from both sides
103.5<(number of phonest imes 3.5)
divdie both sides by 3.5
29.57<number of phones
round up since can't sell a fraction of a phone
30
he has to sell at leas 30 phones

Mr. lang has two sons the sum of their ages 19. the product of their ages is 84. how old is Mr. lang youngest son

kolbaska11 [484]

Answer: The age of Mr. Lang's youngest son is 7 years old.

Step-by-step explanation:

Let's start by listing the factors of 84. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84.

We can only use numbers that are under 19 since we must add up to that total. Now we are left with 1, 2, 3, 4, 6, 7, 12, and 14,

1 can't be an option since 18 is not there to pair with it to add together for 19. For the same reason we can eliminate 2, 3, 4, 6, and 14.

Now we are left with 7 and 12. Let's see is they will work.

7+12=19

7×12=84

It works! Since 7 is the smaller number that's the age of Mr. Lang's youngest son.
