Gale thought that it would be fun to go to the carnival. The carnival cost $15.50 for the first person and $12.00 for each additional person.
Equation: c = 15.5 + 12f
c = cost
f = number of friends
If the input of the equation is 3, what is the output?
in standard form:
you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.
a3+b= 60 (the amount of money you have)
we already know the cost of a=15 so replace a with $15
($15 x 3)+b=60
multiply 15 and 3 to get $45 and replace it with $45
and then replace b with 15 to get the total:
that means you have $15 left after buying 3 dictionaries.
15 divided by the cost of a map ($5) equals 3.
so you can buy 3 maps.
sorry if it was confusing!
after 1 year: 221 deer
30% of 170 is 51. 170+51=221
