stephanie has $645 in her savings account, and she wants to use that money to have a great summer. she spends $40 per week on food, clothes, and books. she wants to have at least $300 left in her account by the end of the summer. which inequality describes the number of weeks stephanie can spend her usual amount without dipping below $300 in her savings account?
a) w< 9
b) w≤9
c) w≤16
d) w< 16

The answer is A caus she is going to spend less than 9
645 - 300 = 345

345 divide by 40 = 8.625 the answer is less 9

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
