18-2(1.5), 18+2(1.5)=15,21

So we want the first option.

error analysis: a contractor purchases 7 dozen pairs of padded work gloves for $99.12. she incorrectly calculates the unit price
chubhunter [2.5K]

Answer:

Unit Price= $1.18

6th grade math help me please !
antiseptic1488 [7]

First we have to figure out how much 3 bags cost using the total cost of $8.25

That means. we would do 8.25/3 and 8.25 divide by 3 equals 2.75.

Now we know that each bag costs approximately $2.75

All we have to do now is multiply 2.75 by 4 to get the cost for the total of 4  bags.

4 times 2.75 is exactly 11 dollars, if might change if theres tax.

But, the answer would be 4 bags costs $11.
