Answer:
£10200
Step-by-step explanation:
Amount borrowed (P) = £6000
Rate of interest (R) = 7%
Time (T) = 10 years
First, let us calculate the simple interest (SI) for 10 years.
Formula for simple interest is given as:

Plugging the values of P, R and T in the above formula, we find:

S.I.= £4200
Total money paid back at the end of the 10 years
= £6000 + £4200
= £10200

Step-by-step explanation:
Answer:
5y+69.50<90
Step-by-step explanation:
You can think of the number of gigabytes he will use as "y", since we don't know the number of gigabytes he will use. The flat cost of one month is $69.50.
You need to add those to calculate the complete cost. The inequality would use a less than sign because he needs to pay less than $90/month. It would not use an inequality sign with a line under it because the problem doesn't say he wants to use $90 or less.
You would solve using basic computation (subtraction and division). Hope this helped!
