Answer:6 weeks
Step-by-step explanation: 5, 10, 20, 40, 80, 160
If seeds are 8 per pound then you need to find the unit rate and make a proportion with how much she spent. So you can make a ratio of 1(pound) / $8 compared to x(pounds) / $10. Then, cross-multiply.
10 = 8x. Divide both sides by 8
10/ 8 = x Simplify the fraction
1 1/4 = x
So, she bought 1 1/4 pounds of seeds
Yes, the two ratios are equivalent. If you multiply both the numerator and the denominator by 6, you will get 18/42.
