A builder requires 35 buckets of mortar to build a wall. Mortar is made by mixing cement and sand in the ratio 1:4

How many buckets of cement and sand does he need?

He needs 7 buckets of cement, and 28 buckets of sane.

Step-by-step explanation:

cement : sand

1:4 = 5

35/5 = 7

7*1=7 .          Cement

7*4=28 .       Sand

The answer is $95923.60

Step-by-step explanation:

Given information is :

p = 2675.32

r = 12% or 0.012.

After 1 year we have 'p' , after 2 years we have p(1+r), after t years we have :

This is a geometric series question with n terms. And n is given as 30 years.

Putting the values in the formula,

= $95923.598 ≈ $95923.60

Hence, the answer is $95923.60
