D. Mrs. Buchanan decided to throw her daughter a sweet sixteen party. She rented a room at a local venue for $500 a night plus $8 per person. If the bill was $1140, how many people attended the party? Mrs. Miller wants to buy a snake that costs $242. She already has $62 and she plans to save $12 per week. In how many weeks will she have enough money to buy the snake?​

Answer:

1) 80 people  2) 15 weeks

Step-by-step explanation:

(x = the number of people)

500 + 8x = 1140  ← ($500 initially plus $8 per person equals $1140)

8x = 640 ←(subtract the $500 from each side)

x = 80 ←(divide by the $8 per person to get the number of people)

------

(x = the number of weeks)

242 = 62 + 12x  ←(The cost of the snake ($242) is equal to her $62 plus $12 she saves every week)

180 = 12x  ←(subtract the $62 from both sides)

15 = x  ←(divide by the $12 per week)
