If a = 3, b = 1, and c =-1, what does (b + c) - (c-a)
equal?
4.
F.
G.
3
H.
0
J. – 2
K. – 4

4

Step-by-step explanation:

a=3

b=1

c=-1

(b + c) - (c-a)

(1+(-1))-((-1)-(3))

Note

+*-= -

+*+=+

-*-=+

So

(1-1)-(-1-3)

0-(-4)

4

(1 - 1) - (-1 - 3)

0 + 4 = 4

Step-by-step explanation:

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!
