    Answer: there are 59059 lbs of gravel.

    Step-by-step explanation:

    In a mixture of​ concrete, there are four lbs of cement mix for each pound of gravel. This means that eight lbs of cement would be mixed for 2 pounds of gravel and 12 lbs of cement would be mixed for 3 pounds of gravel and 12. Therefore, the constant ratio of cement to gravel is 4:1

    The total ratio is 4 + 1 = 5

    If the mixture contains a total of 295295 lb of these two​ ingredients, then the number of pounds of gravel that are​ there is

    1/5 × 295295 = 59059 lbs
