Can someone help please I believe you can put a pdf here

Step-by-step explanation:

The numbers in the box share something in common called AC method.

The two number that is missing must add to get the bottom number while must be a factor of the top number.

For example number 1

The factor of 12 are positive and negative 1,2,3,4,6,12

We can use positve 6 and 2 because 6+2=8

Another example is no.2 the factor of -9 are negative and positve 1,3,9. We can 3 and -3 since they multiply to -9 and add to 0.

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!
