Final answer:

The total cost if one of each item is purchased is $179.15.

Step-by-step explanation:

To find the total cost of purchasing one of each item, we can use the Associative Property of Addition to add the prices together. Let's add the prices:

$175 (graphing paper) + $0.90 (mechanical pencil) + $3.25 (pack of pencil grips)

Using mental math, we can calculate:

$175 + $0.90 + $3.25 = $179.15

Therefore, the total cost if one of each item is purchased is $179.15.

Answer:

(175+0.90)+3.25=175.90+3.25

(Sum would be 179.15)

Step-by-step explanation:

was 175 a typo? if so then it would be

(1.75+0.90)+3.25=2.65+3.25

(Sum would be 5.9, all you need to do is add the numbers in different ways)
