Mark went to the hobby shop and bought 2 lego sets at $38.95 each and some remote car. If he spent a total of $121.85, what was the cost of the remote car?

43.95

Step-by-step explanation:

38.95*2 = 77.9

77.9 + x = 121.85

x = 121.85 - 77.9

x = 43.95

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

is there any other information given for this problem? this is not enough information.
