L: 1750, M:1750-480=1270
Lisa gave some stamps to Mark so Lisa now has 1750-x and Mark has 1270+x. Mark also has 3 times as many as Lisa now: (1750-x)*3=1270+x
5250-3*x=1270+x
4*x=3980, x=3980/4, x=995
So Lisa gave 995 stamps to Mark.
At first Mark had 1270 stamps. Lisa now has 1750-995=755 stamps.
$1.50 because 0.15 x 10 is 1.50

Step-by-step explanation:
65. y = −3x + 2.25 67. y = −x + 12 69. y = 2x + 4. 71. ... the same number, then the values in the table come from a linear ... negative then y will decrease as x increases; if m is zero then y .
