The equation representing the given statement is ~

  • [tex]50x + 330 \geqslant 820[/tex]

The least number of lawns that he can cut and buy the computer is 10 lawns ~

[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]

Total savings should be greater or equal to $ 820 in order to buy the computer,

And his total savinga is equal to ~

Money he saved + money got from cutting lawns.

let's assume the lawns cut by Tyrod be x,

Money earned by cutting lawns is equal to

  • total number of lawns cut × $50

  • 50x

total savings is equal to ~

  • 330 + 50x

hence,

  • [tex]50x + 330 \geqslant 820[/tex]

by solving for " x (number of lawns cut) " we get ~

  • [tex]50x \geqslant 820 - 330[/tex]

  • [tex]50x \geqslant 490[/tex]

  • [tex]x \geqslant 490 \div 50[/tex]

  • [tex]x \geqslant 9.8[/tex]

Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is

  • [tex]10[/tex]
