at sals car repair shop, each of the 8 oil - change stations has a jug of windshield fluid. the graph shows how much fluid is left in each jug. amount of windshield washer fluid. if sal distributes all of the windshield washer fluid equally among the 8 jugs, how much will be in each jug? 1/2 gallon, 7/8 gallon, 1 1/7 gallons, 1 1/2 gallons
Answer
Explanation:
Step1: Count the amount of fluid at each mark
From the graph, there are 2 jugs with 0 gallons, 1 jug with $\frac{1}{2}$ gallon, 2 jugs with 1 gallon, and 3 jugs with $1\frac{1}{2}$ gallons.
Step2: Calculate the total amount of fluid
[ \begin{align*} &(2\times0)+(1\times\frac{1}{2})+(2\times1)+(3\times1\frac{1}{2})\ =&0 + \frac{1}{2}+2+(3\times\frac{3}{2})\ =&\frac{1}{2}+2+\frac{9}{2}\ =&\frac{1 + 4+9}{2}\ =&\frac{14}{2}\ =&7 \end{align*} ]
Step3: Divide the total fluid by the number of jugs
There are 8 jugs. So the amount in each jug is $\frac{7}{8}$ gallon when distributed equally.
Answer:
$\frac{7}{8}$ gallon
