There were 88,800 people at a sporting event.  The 8 in the thousands place is ___ times greater than the 8 in the hundreds place.

• x 10

• x 80

• x 1/10

Fourth grade students at Happy Elementary are making friendship bracelets for a fundraiser. They made 251 red bracelets and 352 blue bracelets. They will sell each bracelet for $4. How much money, m, will they earn if they sell all of the bracelets? 

• 251 + 353 = m

• 1. 352 - 251 = 101

  2. 101 x 4 = m

  
  

• 
  251 + 352 = 603

  603 / 4 = m

• 251 + 352 = 603

  603 x 4 = m

Answer explanation

To find the total earnings, first add the number of red and blue bracelets: 251 + 352 = 603. Then, multiply the total number of bracelets by the price per bracelet: 603 x 4 = m. Thus, the correct choice is 251 + 352 = 603 and 603 x 4 = m.
