Answer:
7 friends
Step-by-step explanation:
Given the inequality expression
17(g+2)+45.99<200
We are to find the value of g that satisfies the inequality
Expand
17g+34 +45.99<200
17g+79.99<200
Subtract 79.99 from both sides
17g+79.99-79.99<200-79.99
17g<120.01
g<120.01/17
g<7.059
Hence the max number of friend that can attend is 7friends.
