Question

Brothers Raymond and Eduardo are saving up money to send their parents on an anniversary vacation. They have calculated that the trip will cost at least $500. If they've already saved $270, how much more do they need to save in order to make enough for the trip?

Answer 1

Given:

Money they've already saved = $270

Trip will cost at least $500.

To find:

The amount they need to save more in order to make enough for the trip.

Solution:

Let they need $x more.

Money they've already saved = $270

Total money they will have = $(x+270)

Now, the trip will cost at least $500. It means, they need $500 or more than that. So, total money they will have needs to be greater than or equal to 500.

$x+270\geq 500$

$x\geq 500-270$

$x\geq 230$

Therefore, they need $230 or more than that to make enough for the trip.
