Can anybody tell me the answer

42 tuna sandwiches, half on white, so 21 on white.  Leaves 21 on brown.

25% of 32 ham sandwiches on brown, so 8 ham on brown.  Leaves 24 ham on white.

20 more white than brown  total,

w = b + 20

w + b = 100

Adding

2w = 120

w = 60

b = 40

Cheese on brown = 40 - 21 - 8 = 11

cheese on white = 60 - 21 - 24 = 15

      T   C   H  Tot

B     21  11   8  40  

W    21  15 24 60

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
