Jane had 27 stickers two weeks ago. She bought the same amount of stickers each day for these two weeks. Now she has 237 sticker

Answer:

Jane bought 15 stickers per day.

Step-by-step explanation:

Given;

Total number of stickers Jane has = 237

Number of stickers 2 weeks ago = 27

To find : Number of stickers she bought each day for two weeks.

Solution,

Let the number of stickers she bought everyday be x.

∴ Number of stickers for 2 weeks = $14\times x=14x$

Now according to question,

Total number of stickers = Number of stickers 2 weeks ago + Number of stickers she bought for 2 weeks

$237=27+14x\\14x=237-27\\14x=210\\x=15$

Thus the number of stickers she bought everyday for 2 weeks is 15.
