tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

To solve this, you need to find the unit price by dividing the cost by the amount. For Mike, divide $2 by 2 to get 1. So, Mike sells hot dogs for $1. Next, divide 2.25 by 3 to get $0.75. So, Sue sells hot dogs for $0.75.

Joe: $1.50

Mike: $1

Jen: $1.25

Sue: $0.75

So, the best deal is Sue because it is the cheapest per unit. Hope this helped!

1. Jadyn started off his long division problem incorrectly. What is his mistake?
Anastaziya [24]

The mistake Jadyn made in the long division is

  • Mistake in subtraction
  • the first quotient

<h3>What is long division ?</h3>

Long division refers to a way of dividing large numbers

performing the long division correctly gives

divisor    dividend     quotient     multiplication    subtraction  new dividend

8             335              40               8 * 40 = 320     335 - 320       15          

8             15                 1                   8 * 1 = 8            15 - 8                7  

8             70                0.8               8 * 8 = 64      70 - 64                6

8             60                0.07             8 * 7 = 56       60 - 56               4

8             40                0.005           8 * 5 = 40       40 - 40               0

The quotient is then added as

40 + 1 + 0.8 + 0.07 + 0.005 = 41.875
