Answer:
27
Step-by-step explanation:
So first we need to plug in 5 as the variable a and -7 as the variable b
4(5)-(-7)
Next we multiply the 4 and the 5 together to get 20
4(5) = 20 or 4 x 5 = 20
20-(-7)
Now we subtract negative 7 from 20
20-(-7) = 27
This can also be written as 20 plus 7 as a mathematical rule states: two negatives make a positive. So:
20-(-7) = 20 + 7
Both of these are equivalent in every sense of the word and give us our final answer of 27

The total amount to be repaid is equal to $949.66
Step-by-step explanation:
Simple interest is a type of interest that is usually applied on short term loans, where when a payment is made towards this kind of interest the payment first goes towards monthly interest, and then the remainder is reverted towards the principal.
FORMULA FOR CALCULATING SIMPLE INTEREST =
Here principal = $922
interest rate = 6%
time period = 6 months (when made per annum it will be 6/12)
SIMPLE INTEREST IS EQUAL TO $27.66
The total amount that is to be repaid is equal to
PRINCIPAL + SIMPLE INTEREST
= $922 + $27.66
= $949.66
