HELP PLS!! INCLUDE EXPLAINING THANK YOU

Lucy paid the least amount of money and she paid $770

Step-by-step explanation:

The way to find dylans is

1000-80= $920

920 x .15= $782

for lucy you do:

1000 x .15= $150

150 + 80= $230

1000-230= $770

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

32/80  

91/140
