The number of weeks required to have enough money in account to buy computer is 12

Solution:

Given that Maya has $210 in a savings account for a new computer the computer cost $537.15 including sales tax

At the end of each week she deposits $27 into the account

To find: number of weeks required to have enough money in the account for the computer

Total cost of computer = $ 537.15

Amount in savings account = $ 210

Let "a" be the number of weeks required to have enough money in account to buy computer

Each week she deposits $27 into the account

So we can we frame a equation as:

total cost of computer = Amount in savings account + (number of weeks x 27)

Thus number of weeks required is 12 approximately

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
