He needs to earn ; 77.99-20= 57.99 dollars

so in one week there are 2 weekends; so he earns 6×3×2 = 36 dollars

so no of week = 57.99÷ 36= 1.6 weeks

so weeks are in natural no thus it will take him 2 weeks !!

4 weeks because he earns 18 dollars per weekend so 18 multiplied by 4 plus 20 is 92 which gives him enough to get the new skateboard and the reason why it’s not 3 is because 3 multiplied by 18 plus 20 is not enough for the skateboard
