Asmall dog gets fed 3/4 cups of dog food twice a day. using d for the number of days and f for the amount of dog food in cups, write an equation relating the variables. use the equation to find how many days a large bag of dog food will last if it contains 210 cups of food?

The desired equation relating the variables is;

Also, a large bag of dog food that contains 210 cups of food will last 140 days according to the equation.

According to the question;

The small dog gets fed 3/4 cups of dog food twice a day.

In essence; The dog is fed twice a day with 3/4 cups of dog food each time.

Therefore; The dog gets fed 2× (3/4) cups of dog food per day

a) The equation is therefore;

b) To determine the number of days a large bag of dog food will last if it contains 210 cups of food;

Step-by-step explanation:

d1 = 4 * 210 / 3 = 280 days

1e+27

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
