M8 (Friday, Sept 11 th ) (1) Some friends decided to go to the aquarium. Each person pays $7.50 to get in the aquarium. They spend a total of $40 for the shark exhibit. The total cost is $70. What is the cost per person? Define the variable, set up an equation and solve the equation.

M8 (Friday, Sept 11 th ) KEY Answer : Define variable: X = # of friends/persons Equation set up: $7.50x + $40 = $70 Answer x = 4

M8 (Monday, Sept 14 th ) Faith spent $78 at the Fashion Warehouse sale. She bought 2 t-shirts that cost $14.50 each and 2 pairs of shoes that cost the same amount. How much did she spend for one pair of shoes?

M8 (Monday, Sept 14 th ) KEY Answer: Let s = the cost of one pair of shoes 2(14.50) + 2s = s = s = s = = 2 Check: (24.50) = One pair of shoes cost $24.50.

M8 (Tues, Sept 15 th ) Solve each equation combining like terms (1)x x = (2) -5n – 2n = V = 10

M8 (Wed, Sept 16 th ) Solve each equation using the distributive property 1.8v – 4(v+8) = 8 2.-(x-4)= 20 x = 10 x = -16

M8 (Thur, Sept 17 th ) Solve each equation 1.36 – 4a – 3a = (p – 5) + 8 = 17 a = 2 p = 8

M8 (Mon, Sept 28 th ) x = 8 a = 5 Solve the multi-step equations below: 1. 11x = x 2. 2a – 31 = -9a + 24

M8 (Tues, Sept 29t h ) n = 4 No solution Solve the equation with variables on both sides: 1.7n – 2 = 5n x -3 + x = 5x x

M8 (Thurs, Oct 1st) x = 66 Solve the equations by clearing the fraction:

M8 (Fri, Oct 2nd) -22 = -4 (no solution) Solve the multi-step equation below: (1) 24x – 22 = -4( 1- 6x)
