A jacket costs $47.85, and a tax of $3.92 is added.

  • What is the final price?
  • If a customer pays with $60, how much change do they get?

A scientist measures a snake at 2.15 meters. The snake grows 0.28 meters per month.

  • How much longer will the snake be after one year?
  • What will its total length be after one year?
  • If another snake is 5.35 meters, which snake is longer?
  • 0.28 × 12 = 3.36 meters of growth in one year
  • 2.15 + 3.36 = 5.51 meters total length
  • The first snake (5.51 meters) is longer than the second snake (5.35 meters).

Sanjana buys a notebook for $6.85, a pen for $4.90, and a ruler for $5.75.

  • How much does she spend in total?
  • If she pays with a $15 bill, does she have enough money? If not, how much is she short?


  • $6.85 + $4.90 + $5.75 = $17.50
  • $15.00 - $17.50 = -$2.50 → She is $2.50 short.

Four students competed in a track tournament, and their race times (in seconds) were recorded:

  • Liam: 15.2 seconds

  • Sophia: 14.9 seconds

  • Jackson: 16.1 seconds

  • Ava: 14.7 seconds

  • Who had the fastest time (shortest time)?

  • Who had the slowest time (longest time)?

  • What is the difference in time between the fastest and slowest runner?

  • Fastest time: Ava (14.7 seconds)
  • Slowest time: Jackson (16.1 seconds)
  • Difference: 16.1 - 14.7 = 1.4 seconds

Four students competed in a track tournament and recorded their race speeds in meters per second:

  • Liam: 7.85 m/s

  • Sophia: 8.02 m/s

  • Jackson: 7.97 m/s

  • Ava: 8.1 m/s

  • Who ran the fastest?

  • Who ran the slowest?

  • What is the difference in speed between the fastest and slowest runner?

  • Fastest: Ava (8.1 m/s)
  • Slowest: Liam (7.85 m/s)
  • Difference: 8.1 - 7.85 = 0.25 m/s

in a race speed problem, the higher number means a faster speed because speed is measured in meters per second (m/s)—so the more meters per second, the faster the runner.
