Question

the table and the graph blow show josie and slavadors wages respectively based on the number of hours worked

Answer 1

(a)$8.75

(b)$7.5

(c)$60

Step-by-step explanation:

Part A

From the table, for 3 hours, Josie earned a wage of $26.25.

Therefore:

`\begin{gathered} \text{Josie's hourly wage=}(26.25)/(3) \\ =\$8.75 \end{gathered}`

Part B

From the graph:

When Salvadorhours worked = 2

Wages = $15

Therefore:

`\begin{gathered} \text{Salvador's hourly wage=}(15)/(2) \\ =\$7.5 \end{gathered}`

Part C

Each week, they worked for 8-hours daily for six days.

The total number of hours they worked in a week

`\begin{gathered} =6*8 \\ =48\text{ hours} \end{gathered}`

Next, we calculate their earnings after one week.

`\begin{gathered} \text{Josie's earning=}8.75*48=420 \\ \text{Salvador's earning=}7.5*48=360 \\ \text{Difference}=420-360=\$60 \end{gathered}`

The difference in Josie's and Salvador's earning after one week is $60.
