Change=given-cost
cost=total cost=cost for all of them added together
cost=popcorn+small drink+fruit snacks
cost=4+3+5
cost=12
given=x
change=3
3=x-12
that is the equation
solve
add 12 to both sides
15=x
he gave $15 to the cashier
Let's see, if the first one has a Principal of $50, when it doubles the accumulated amount will then be $100,
recall your logarithm rules for an exponential,



now, for the second amount, if the Principal is 500, the accumulated amount is 1000 when doubled,


now, for the last, Principal is 1700, amount is then 3400,

of means times so you multiply the fractions
1 x 9 = 9
3 x 16 = 48 (we multiplied numerators and denominators)
9/48 = 3/16 (Simplify by dividing a multiple on both the numerator and denominator
Answer:
