3 0

Answer:

302

Step-by-step explanation:

7 goes into 21 3 times, so the first digit of the quotient is 3. There's no remainder. Bringing down the second "1," we find this indivisible by 7, and so bring down the 6.Thus, Remember that 7 goes into 14 2 times. Thus, a good estimate would be 302.

Answer:

C 14 bars, 11 sticks

Step-by-step explanation:

It seems to be easiest to simply try the answers and see what adds up.

A) 2×12 +3×13 = 24 +39 ≠ 61

B) 2×11 + 3×14 = 22 +42 ≠ 61

C) 2×14 +3×11 = 28 +33 = 61 . . . correct answer choice

D) 2×10 +3×15 = 20 +45 ≠ 61

If you want to solve the equations, it can work well to let s represent the number of sugar sticks (the higher cost item). Then the revenue equation is ...

2(25 -s) +3s = 61

50 +s = 61

s = 11 . . . . . . . matches answer choice C
