Answer:
5 small beads!
Step-by-step explanation:
Hey there!
If large beads are $3 each, and she buys 5 of them, our equation is $3 x 5 which equals $15. So Cara will spend $15 buying large beads.
Cara has $10 left now, because $25 - $15 = $10. Since each small bead is $2, we divide $10 (the total amount of money she has) by $2 (the cost of each bead). This will tell us how many she can buy! So $10 ÷ $2 is 5. Cara can buy 5 small beads!
I hope this helped you! Rating my answer and giving it a Thanks would sure help me out!

Answer:
I would say 1 lbs of dog food is equivalent to 4 4/7 meals.
7/8 lbs : 4 meal = 1 lbs : x meals 1 lbs = 8/8 lbs perform cross 7/8 lbs (x) = 8/8 * 4 7x/8 = 8*4 / 8*1 7x/8 = 32/8 7x/8 = 4 8(7x/8) = 8*4 7x = 32 7x/7 = 32/7 x = 4 4/7 meals to 7/8 : 4 = 1 : 4 4/7 7/8 * 32/7 = 4 * 1 224/56 = 4 4 = 4
