Highlighter pens cost $3.86 per set at an office supply store. Which equation can be used to determine the price, P, of n sets of these pens? (1 point) a n = 3.86P b P equals 3.86 over n c n equals 3.86 over P d P = 3.86n At an adventure park, a base ticket costs $85.50 per adult. Which equation can be used to calculate the base ticket price, A, for n adults? (1 point) a n = 85.50A b A = 85.50n c n equals 85.50 over A d A equals 85.50 over n

1. d) P = 3.86n

2. b) A = 85.50n

Step-by-step explanation:

step-by-step explanation:

step 1: simplify both sides of the equation.

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
