sales month	jan	feb	mar	apr	may

a. bar graph with jan: ~500, feb: ~3000, mar: ~4500, apr: ~5000, may: ~4000
b. bar graph with jan: ~500, feb: ~4500, mar: ~5000, apr: ~4000, may: ~3000
c. bar graph with jan: ~5000, feb: ~3000, mar: ~500, apr: ~0, may: ~4000

Explanation:

Step1: Sum all balloon counts

$794 + 741 + 368$

Step2: Calculate first sum

$794 + 741 = 1535$

Step3: Add remaining balloon count

$1535 + 368 = 1903$

Step1: Sum people who left

$170 + 784$

Step2: Calculate total people who left

$170 + 784 = 954$

Step3: Subtract from initial count

$1577 - 954 = 623$

Step1: Multiply elephants by daily water

$2 \times 9$

Step2: Calculate total water

$2 \times 9 = 18$

Step1: Divide total money by toy cost

$\frac{15}{3}$

Step2: Calculate number of toys

$\frac{15}{3} = 5$

Step1: Match table values to graphs

Jan:500, Feb:4500, Mar:5000, Apr:4000, May:3000. Compare to Graph A's bar heights.

Answer:

1. 1903
2. 623
3. 18
4. 5
5. A. The bar graph with Jan: ~500, Feb: ~3000, Mar: ~4000, Apr: ~5000, May: ~3000
