121/2 = 720/p
720*2= 121p
1440=121p
divide by 121
=12%
Elena's total cost (C) is 5(9.98 + 24.99 + x)
Since each dog leashes cost $9.98, each bag of dog food cost $24.99 and each crate of egg cost $x, hence:
Total cost (C) = 5 * $9.98 + (5 * 24.99) + (5 * x)
C = 5(9.98 + 24.99 + x)
Therefore Elena's total cost (C) is 5(9.98 + 24.99 + x)

Answer:

Step-by-step explanation:








If you would like to know how many dolls did Bob and Carol break today, you can calculate this using the following steps:
On average, they break: 12% of 175 = 12/100 * 175 = 21 dolls.
Today: 2/3 as many dolls as usual = 2/3 * 21 = 14 dolls
Result: Bob and Carol broke 14 dolls today.
