Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring. Write a linear equation that models their total earnings for traveling and tutoring for a given number of hours.

30 + 10.50h

Step-by-step explanation:

From the question, we are informed that Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring.

The linear equation that models their total earnings for traveling and tutoring for a given number of hours would be written as:

= $30 + $10.50h

where h represents the number of hours for tutoring used.

For example, if 2 hours if tutoring was used, the total amount earned would be:

= 30 + 10.50h

= 30 + 10.50(2)

= 30 + 21

= $51

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
