Question

Prudie needs $90 or more to be able to take her family out to dinner. She has already saved $30 and wants to take her family out to eat in 4 days . Suppose that Prudie earns the same each day . Write an inequality to find out how much she earns each day... whats the inequality?

Answer 1

90≤4x+30

Yes she will have enough. 4 multiplied by 18 is 72. 72+30=102. 

Hope this helped.
