A family of 5 comes to the amusement park. There are two adults and three children (under the age of 12). They qualify for a special family rate of $174.45. The clerk tells them that a child's ticket always costs $11 less than an adult's ticket. Write an expression to represent the cost of the child's ticket in terms of the adult ticket. Remember the child's ticket is $11 less than the adult's ticket.
let a = the cost of an adult ticket, then a-11 is the cost of a child's ticket (the way the question is phrased, this is the answer) this is an equation that represents the family situation 2a+3(a-11)=174.45 since there are 2 adults that pay $a and three children that pay $(a-11) each
so the last equation represents the cost of a childs ticket
a-11 is the cost of a child's ticket written in terms of the cost, a, of an adults ticket. if you are writing the answer, you should write: let a = the cost of an adult ticket, then a-11 is the cost of a child's ticket
thanks this is part of a big project mind if i ask a few questions?
soif for example an adults ticket cost $20 then a childs will be 11 dolars less, or 20-11=$9
shoot
ok kool i thing i get it it seems pretty easy so far but im not good at math
2a+3(a-11)=174.45 i have to solve this wud it b 2a+3a-33=174.45 5a-33=174.45 +33 +33 5a=207.45 / 5 x=41.45?
a=41.49 (not 45)
yes my mistake but the rest is correct?? wow i feel kinda smart haha ok ummm i think i have like 2 more questions
yup
ok and tht wud be the value of an adult ticket?
correct
so all i have to do wud be subtract 11 and tht wud be tha childs ticket
yepper
yaaay haha thnx
you are kinda smart in math!
hahaha yea i guess...not really :/
umm ihave a part two i just asked the question wud u mind working with me to get it?
ok
