Answer:
A. 10 bricks
B. 4 pounds
Step-by-step explanation:
Water = 39 pounds
brick dust = 48 pounds
Total mixture = water + brick dust
= 39 + 48
= 87 pounds
She spills 13 pounds of the mixture while stirring
Remaining mixture = Total mixture - Spillage
= 87 pounds - 13 pounds
= 74 pounds
The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture
Number of bricks made = Remaining mixture / pounds per brick
= 74 pounds / 7 pounds
= 10 bricks remaining 4 pounds of the mixture

Answer:
The original cost was 20 dollars.
Step-by-step explanation:
$12 represents 60% of the original price.
Set up a proportion
Cross multiply Reduce 100/100 to 1
60/100 * x = 12 * 100/100
Multiply by 100
60/ 100 * x = 12
Divide by 60
60x = 12*100
60x = 1200
60x/60 = 1200/60
x = 20 dollars.
