Answer:To question 1: van=9, bus=60To question 2: Sorry, I don't know the answer.To question 3: skate rental fee=$2.50, admission fee=$3.25Step-by-step explanation:Question 1:Step 1 - set up equations14v+16b=1,08610b+13n=870Step 2 - Solve for variable (in this case v)10v+13b=870Subtract 13b from both sides10v=-13b+870Divide both sides by 10V=-1.3b+87Step 3 - substitute the v in equation and solve14 (-1.3b+87)+16b=1,086-18.2b+1,218+16b=1,086Combine like-terms-2.2b+1,218=1,087Subtract 1,218 from both sides-2.2b=-132Divide both sides by -2.2B=60Step 4 - substitute for b and solve10v+13(60)=87010v+780=870Subtract 780 from both sides10v=90Divide both sides by 10V=9Question 3:Step 1 - set up equations5s+6f=325s+7f=35.25Step 2 - solve for variable (in this case s)5s+6f=32Subtract 6f from both sides5s=-6f+32Divide both sides by 5S=-1.2f+6.4Step 3 - substitute for s and solve5(-1.2f+6.4)+7f=35.25-6f+32+7f=35.25Combine like-termsF+32=35.25Subtract 32 from both sidesF=3.25Step 4 - substitute for f5s+6(3.25)=325s+19.5=32Subtract 19.5 from both sides5s=12.5Divide both sides by 5S=2.5
