7.89 greater or less than 7.189<br><br> 6.030 greater less or equal 6.03
NemiM [27]
7.89 is greater than 7.189,  6.03 is equal to 6.030, because that last zero doesn't really change anything it cancels itself out

James estimated the total cost of groceries to be $50. The actual cost of the groceries is $65. What is the percent error? Round
Alex777 [14]

To get percent error you take actual-predicted and divide by the actual then multiply by 100 to get the percent.

65-50=15

15/60=0.25

0.25 times 100 =25%

The correct answer is C. Let’s break this down with the distributive property.

5(6x+6)

30x+30

5(9-x)

45-5x

Now add and subtract like terms.
30x-5x=25x

30+45=75

Put the remaining numbers together.
25x+75 and there you go.
