Keisha solved the following equation: 4x − 2x + 8 = 6(x + 4)

StepWorkJustification
1 2x + 8 = 6(x + 4)Combine like terms
2 2x + 8 = 6x + 24Associative Property of Multiplication
3−4x + 8 = 24Subtraction Property of Equality
4 −4x = 16Subtraction Property of Equality
5 x = −4Division Property of Equality

Which step has an incorrect justification?
Step 1
Step 2
Step 3

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

$450 i think. hope this ☺
