Susan Marciano invested part of her $ 12 comma 000 bonus in a fund that paid an 11 % profit and invested the rest in stock that suffered a 3 % loss. Find the amount of each investment if her overall net profit was $ 760

$8000

Step-by-step explanation:

We have to x the amount invested in funds they earned, that is 11%.

Therefore, the amount invested in stocks that suffered a 3% loss is 12000 - x.

The return on investment in funds is: 0.11 * x

The loss on the stock investment is: 0.03 * (12000 - x).

The net profit is:

 0.11 * x - 0.03 * (12000 - x).

Since the net profit given in the problem is $ 760, we have:

0.11 * x - 0.03 * (12000 - x) = 760

We solve for x, we have:

0.11 * x - 0.03 * (12000 - x) = 760

0.11 * x - 360 + 0.3 * x = 760

0.14 * x = 760 + 360

x = 1120 / 0.14

x = 8000

So,

the amount invested in funds that earned 11% is 8000.

the amount invested in stocks that suffered a 3% loss is 12000 - x = 12000 - 8000 = 4000.

5/12, or 5: 12

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!
