Answer:
x = -9
Step-by-step explanation:
x = unknown
x+5 = -4
reverse it
-5 + -4 = -9
this will work from the fact that if x is equal to 5 more than -4 you would reverse it so that it is negative 4 - 5 which would be -9
arithmetic progression problem
Interest = $75
Total to pay back = $375
The total amount she will have to pay back is found by the formula:
= Amount borrowed * (1 + rate * years)
= 300 * ( 1 + 5% * 5)
= $375
The interest is therefore:
= Amount to be paid back - Amount borrowed
= 375 - 300
= $75
