Luca sells muffins and juice boxes at the
rosijanka [135]

Answer:

1.5m+1.25j

Step-by-step explanation:

m equals the number of muffins sold, and because each muffin sells for $1.50, 1.5m represents the income made from the muffins.

Same thing with the juice boxes, j equals the number of juice boxes sold, and because each juice box sells for $1.25, 1.25j represents the income made from the juice boxes.

Add the income from both of them to get the total income, and you get 1.5m+1.25j.

Josh invested $12,000 in mutual funds and received a sum of $20,000 at the end of the investment period. Calculate the ROI.
tresset_1 [31]

Answer:

ROI = 66.67%

Step-by-step explanation:

Given:

josh investment= $12,000

Received sum= $20,000

ROI=?

ROI is the return on investment that gives the loss or gain in any investment and is calculated by the following formula:

ROI= (interest/investment) x 100

Finding interest:

interests= received sum- investment

              = 20,000-12,000

              =8000

Putting values in ROI formula we get:

ROI= (8000/12000) x 100

      = 66.67%

Hence the return on investment is 66.67%!

If $95 is put in an account that gets 6% and I add $18 at the end of each year, how much will I have at the end of 11 years?
Temka [501]
6% of $95 = $5.70
multiply $5.70 by 11 years = $62.70 <— interest gained over 11 years
multiply $18 by 11 years = $198 <— total added over 11 years 
add $95 + $62.70 + $198 = $355.70
there will be a total of $355.70 in your account after 11 years
