Jackie is reading a 252 page novel for her summer reading project. On Monday she reads 4/8 of the novel. On Tuesday she reads 28
natima [27]

So far, Jackie has read 217 pages

In order to determine the total number of pages Jackie read, we would have to determine the number of pages she read each day and add these pages together

  • Number of pages she read on Monday = \frac{4}{8} x 252 = 126 pages
  • Number of pages she read on Tuesday = 28 pages
  • Number of pages she read on Wednesday = \frac{1}{4} x 252 = 63 pages

The total number of pages she has read so far = 126 + 28 + 63 = 217 pages

$46 shoes; 2.9% tax some one please help me and i'm new in this site
ZanzabumX [31]
If you would like to know the value of the 2.9% tax, you can calculate this using the following steps:

2.9% tax of $46 shoes = 2.9% * 46 = 2.9/100 * 46 = $1.334

If you would like to know what is the whole price you have to pay for the shoes (including the tax), you have to add $46 and $1.334:

$46 + $1.334 = $47.334

If x is an odd number, write an expression for the odd number that directly follows x.
LenKa [72]
I believe the expression would be:

x+2

For example, if you have the odd number 3 as x, 3+2 would be 5, the next odd number.
Hope this helped!! xx
