Show a way to count from 668 to 900 using ones, tens, and hundreds
zmey [24]

Answer

668 + 232 ones = 900

or

668 + 23 tens + 2 ones = 900

or

668 + 2 hundreds + 32 ones = 900

or

668 + 2 hundreds + 3 tens + 2 ones.

<u>Explanations</u>

900 - 668 = 232. Meaning we can add 232 ones to 668 to get 900.

232-200 = 32 ⇒ Meaning, we can add 2 hundreds and 32 ones to 668 to get 900.

32-30 = 2. This means we can add 2 hundreds, 3 tens and 2 ones to 668 to get 900.

900 - 668 = 232

hodyreva [135]

Answer:

$36.4

Step-by-step explanation:

Given

Cost of Jean = $56

Percent markdown = 35%

Discount = 35% of $56

Discount = 0.35 * 56

Discount = $19.6

New price = $56 - (35% of $56)

New price = $56 - 19.6

New price = $36.4

hence the price that will replace B is $36.4
