Question

Billy's Bagels sells bagels and sandwiches. The profit on every bagel is $2 and the profit on every sandwich is $3. Billy made a profit of $1,560 last week.
a. Write an equation in a standard form that represents Billy's profits last week, where x is the number of bagels sold and y is the number of sandwiches sold.
b. Change the equation for Billy's profit to slope-intercept form.
c. Write the equation in function notation. HELP!!

Answer 1

Answer:

a. 2x + 3y = 1560

b. y = -2x/3 + 520

c. f(x) = -2x/3 + 520

Step-by-step explanation:

a. We are told that the profit on each Bagel is $2 for x bagels and $3 for each sandwich is $3

for a total of y sandwiches

So we have;

2x + 3y = 1560

b. Slope intercept form is generally

y = mx + b

So we have

3y = -2x + 1560

y = -2x/3 + 520

c. In function notation;

f(x) = -2x/3 + 520
