Answer:
21 N
Step-by-step explanation:
let mass be m and weight be w
Given w varies directly with m then the equation relating them is
w = km ← k is the constant of variation
To find k use the condition m = 7 , w = 49 , then
49 = 7k ( divide both sides by 7 )
7 = k
w = 7m ← equation of variation
When m = 3 , then
w = 7 × 3 = 21 N

At 11 am Lacy get's paid around 50 dollars for something such as work. The money sits in her purse until 1:15pm when she pays for something such as food.
245 feet
340 - 130 + 80 - 45 = x
340 - 95 = x
x = 245 feet
