Each week he earns $142.5 from his partime job plus $25 from chores and then saves 85% of that total ($167.5). 85x167.5 = 14237.5 divided by 100 = 142.375 which is 85% of what he earns each week. Then multiply that by 8 weeks to find his total on August 25th. The answer should be $1,139

Sara was thinking of a number. Sara halves the number and gets an answer of 38.5. Form an equation with x for the information
lbvjy [14]

Answer:The equation wth x in the information can be written as

1/2 x = 38.5 , Upon solving, the number = 77

Step-by-step explanation:

Let the number Sara was thinking about be x

halving the number to get an answer = 38.5 can be expressed as

 1/2 X = 38.5

The equation with x in the information can be written as

1/2 x = 38.5

solving it becomes

1/2 x= 38.5

x = 38.5 x 2

x=77

The number Sara was thinking about = 77
