Which shows a correct order to solve this story problem? Kent and Curtis went to the state fair. They had to pay a total of $7.18 sales tax on everything they bought. They spent $22.50 for each admission ticket and $35.50 altogether for food. They split all the costs evenly. How much did each boy pay? A. Step 1: Calculate the price of 2 admission tickets. Step 2: Add that amount to the amount spent on food and the tax. Step 3: Divide by 2. B. Step 1: Double the amount for 1 admission ticket. Step 2: Take half of the amount spent on food and add the total from Step 1 plus the tax. Step 3: Divide by 2. C. Step 1: Add $22.50 and $35.50. Step 2: Divide the total by 2. Step 3: Add the amount of the tax.

The coordinates of the vertices of trapezoid EFGH are E(-8, 8),F(-4, 12), G(-4, 0), and H(-8, 4). Thecoordinates of the vertices of trapezoid E’F’G’H’ are E’(-8, 6), F’(-5, 9),G’(5, 0), and H’(-8, 3). Which statement correctly describes the relationship betweentrapezoid EFGH and trapezoid E’F’G’H’? a) Trapezoid EFGH is congruent to trapezoid E’F’G’H’ because youcan map trapezoid EFGH to trapezoid E’F’G’H’ by reflecting it across the x-axisand then translating it up 14 units, which is a sequence of rigid motions.b) Trapezoid EFGH is congruent to trapezoid E’F’G’H’ because youcan map trapezoid EFGH to trapezoid E’F’G’H’ by translating it down 2 units andthen reflecting it over the y-axis, which is a sequence of rigid motionsc) Trapezoid EFGH is congruent to trapezoid E’F’G’H’ because youcan map trapezoid EFGH to trapezoid E’F’G’H’ by dilating it by a factor of 34and then translating it 2 units left, which is a sequence of rigid motionsd) Trapezoid EFGH is not congruent to trapezoid E’F’G’H’ because there isno sequence of rigid motions that map trapezoid EFGH to trapezoid E’F’G’H’.
