Sara has two puppies, Sonny & Cher. Every month she purchases enough food to feed her puppies for the month. Sonny eats 8.25 cans of food per week. Cher eats 15 1/2 cans of food per week. Sara purchases a 40 can variety pack of Cute Puppy food that costs $21. Determine the number of 40 can packages of Cute Puppy that Sara needs to purchase to feed her puppies for one month. Use 4 weeks or 28 days to represent a month
Help, please

Total number of cans per week: 8.25 + 15.5 = 23.75 cans

23.75 cans per week x 4 weeks = 95 cans per month

95 cans /  40 cans per package = 2.375 cases per month

Round up to 3 cases.

She needs to buy 3 cases a month

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
