First, you would need to determine how much it would cost her if it was three for $1 or seven for 42.
Three for $1:
21 ÷ 3 = 7
7 × $1.00 = $7.00
Seven for $2:
21 ÷ 7 = 3
3 × $2.00 = $6.00
Now, all you would need to do is find the difference.
$7.00 - $6.00 = $1.00
Jackie would have saved A. $1.00.
I hope this helps!

Answer:
-24
Step-by-step explanation:
Since only one of the factors has a negative sign, the product will be negative.
4 · (-6) = <u>-24</u>
Answer:
The answer is C. 546.
If a population decreases by 11%, that means that 89% (100% - 11% = 89%) of cheetahs remains each number. 89% can be expressed as 0.89, so to calculate the change of the population, we must each year multiply the number of cheetahs by 0.89.
After 1 year: 1750 * 0.89 ≈ 1558
After 2 years: 1558 * 0.89 ≈ 1387
After 3 years: 1387 * 0.89 ≈ 1234
After 4 years: 1234 * 0.89 ≈ 1098
After 5 years: 1098 * 0.89 ≈ 977
After 6 years: 977 * 0.89 ≈ 870
After 7 years: 870 * 0.89 ≈ 774
After 8 years: 774 * 0.89 ≈ 689
After 9 years: 689 * 0.89 ≈ 613
After 10 years: 613 * 0.89 ≈ 546
