Bert already has $50 but needs a total of at least $250 for his holiday. He gets paid £20 day for delivering papers. What is the least number of days he must work to get enough money for his holiday?

Respuesta :

Bret would need to work for 8 days. He has $50 and need to pay $250. 250-50= 200. £20 is $27.59 200/27.59 =7.24 If £20 is a typo then 10 days.

Answer: Hi!

We know that Bert has $50, but he needs a total of at least $250 for this holiday. The differences between what he needs and what he has is:

$250 - $50 = $200

So he needs another $200.

He gets paid £20 a day and we want to know the number of days that he needs to work in order to obtain the $200.

The first step is to transform the £20 into dollars.

£1 = $1.27

then his daily pay in dollars is: 20*$1.27 = $25.4

Now let's call X the number of days that he needs to work to obtain the $200, we got:

X*$25.4 = $200

X = $200/$25.4 = 7.8

We should round up this result because we want a whole number.

X = 8, this means that Bert needs to work at least 8 days if he wants to have at least $250 for the holidays.
