WILL GIVE LOTS OF POINTS HELP SOLVE SOON, NUMBER 7
Nadusha1986 [10]

Answer: 4x + 3 = 39

Tyrod needs at least $820 to buy the computer he wants. He has already saved $330. He earns $50 per lawn that he cuts. What is t
Ksju [112]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

The equation representing the given statement is ~

  • 50x + 330 \geqslant 820

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

\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}

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,

  • 50x + 330 \geqslant 820

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

  • 50x  \geqslant 820 - 330

  • 50x \geqslant 490

  • x  \geqslant 490 \div 50

  • x \geqslant 9.8

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

  • 10
