Subtract the amount she has saved from the price of the laptop:
849 - 232 = 617
Now divide the amount she still needs by the amount she saves per week:
617 / 28 = 22.04
Because the answer has a number to the right of the decimal, she will need to save for 23 full weeks to have enough money.
If she saves for 22 weeks, she would be $1 short:
22 x 28 = 616 + 232 = 848
Area covered by the solar cells = 269.5 m^2
Area of one cell = 150 cm^2
Convert the area of one cell to m^2 by using the conversion factor 1m^2 = (100cm)^2 => 1 = 1m^2 / 1000 cm^2
=> 150 cm^2 * [1m^2 / 1000 cm^2] = 0.150 m^2
Now finf the number of times that 0.150 is contained in 269.5 by dividing 269.5 by 0.150
269.5 = 0.150 = 1,796.67
Which means that the number of cells is betwee 1796 and 1797.
