Admission rate at local aquarium :

Ticket ________ Price

Children _______ $9

Adult __________ $15

Mr.Reilly spent $90 on tickets to the aquarium. Write an equation in standard form to represent the situation

Answer:

y = 6 - (9/15)x

Step-by-step explanation:

The amount spent = [(rate of children ticket * number of children ticket obtained) * rate of adult ticket * number of adult ticket purchases)]

Let :

number of chikdren ticket = x

Number of adult ticket = y

(15 * y) + (9 * x) = 90

15y + 9x = 90

15y = 90 - 9x

Divide through by 15

y = 6 - (9/15)x

She worked 2 and 1/2 hours yesterday, and today she did 4 and 1/4 hours.

first off, let's check how many hours she worked total, and divide 54 by it.

so, first off, let's convert the mixed fractions to "improper" and add them up.

$\bf \stackrel{mixed}{2\frac{1}{2}}\implies \cfrac{2\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{5}{2}}
\\\\\\
\stackrel{mixed}{4\frac{1}{4}}\implies \cfrac{4\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{17}{4}}\\\\
-------------------------------$

$\bf \cfrac{5}{2}+\cfrac{17}{4}\impliedby \textit{our LCD will be 4}\implies \cfrac{(2\cdot 5)+(1\cdot 17)}{4}
\\\\\\
\cfrac{10+17}{4}\implies \cfrac{27}{4}\implies \stackrel{total~hours}{6\frac{3}{4}}
\\\\\\
\cfrac{\stackrel{wages}{54}}{\stackrel{hours}{6\frac{3}{4}}}\implies \cfrac{54}{\frac{27}{4}}\implies \cfrac{\frac{54}{1}}{\frac{27}{4}}\implies \cfrac{54}{1}\cdot \cfrac{4}{27}\implies \cfrac{216}{27}\implies 8~\frac{\$}{hr}$
