Can you please help me with this question is hard and i will give you a Brainiest

Not too hard.  Pro tip: Get really good at algebra and most math classes become easy.  Physics too.

25y = 15y + 75

We subtract 15y to both sides.  I'll write it out, but that's just a baby step that you should learn to skip.

25y - 15y = 15y + 75 - 15y

We could have just directly written

10y = 75

Dividing both sides by 10 we get

y = 75/10 = 7.5

y=7.5,  bottom left

answer: the answer is ann

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!
