Answer: D.
Step-by-step explanation:
If they already have 565 cans and 87 will bring cans then we could represent it by the inequality Â
87x + 565[tex]\geq[/tex] 1000 Â where x is the number of cans each guest much bring to meet the goal. so solve for x.
87x  + 565[tex]\geq[/tex] 1000
    -565   -565
87x [tex]\geq[/tex] 435
x [tex]\geq[/tex] Â 5 Â
since we now that x is 5 Â then A Â and C can't be answers.
B can't be an answer in this case because 5 is excluded but they actually need at least 1000 bottles so 5 needs to be excluded.
