3r = 10 + 5s, where r = 10
Substitute 10 for r.
3(10) = 10 + 5s
30 = 10 + 5s
Subtract 10 from each side.
20 = 5s
Divide by 5.
4 = s

The local deli charges a fee for delivery. On monday, they delivered two dozen bagels to an office at a local cost of $8. On Tue

aev [14]

Answer:

2b+f=8; 3b+f=11
b=3, f=2

Step-by-step explanation:

The problem statement defines the variables and gives the relations ...

2b + f = 8 . . . . total cost on Monday

3b + f = 11 . . . . total cost on Tuesday

Subtracting the first equation from the second, we get ...

(3b +f) -(2b +f) = 11 -8

b = 3 . . . . . simplify

Substituting this into the first equation, we can solve for f

2·3 +f = 8

f = 2 . . . . . . . subtract 6

Bagels cost $3 per dozen; the delivery fee is $2.
