The answer would be $22.68!

If Andy bought 3 paintbrushes for $1.75 each, then we just multiply how much they cost by the number that the bought.

1.75 x 3 = 5.25

If Andy bought 7 tubes of oil paint, we just do the same thing we did in the first step! Multiply how much they cost by the number that the bought.

2.49 x 7 =

The answer is 22.68 dollars.

This is the answer because 3 x $1.75 = 5.25
Then 7 x $2.49 = 14.43
14.43 + 5.25 = 22.68

Aron charges an initial service fee of 10$ plus 15$ per hour , what is X?
Marysya12 [62]

Answer:

The linear function becomes:

y = 15x + 10

Here, 'x' is the number of hours, b=10 is the initial service fee i.e. $10, 15 is slope or rate of change, and 'y' is the cost.

Step-by-step explanation:

We know that the slope-intercept of a linear function is

y = mx+b

where m is the slope and b is the y-intercept

Note: Slope is also termed as the 'rate of change'.

Given that Aron charges an initial service fee of 10$.

Thus, the y-intercept = b = 10

As the rate of change = 15$ per hour

so the slope = m = 15

Therefore, the linear function becomes:

y = mx+b

y = 15x + 10

Here, 'x' is the number of hours, b=10 is the initial service fee i.e. $10, 15 is slope or rate of change, and 'y' is the cost.

For example, in one hour i.e. x = 1, the cost 'y' will be:

y = 15x + 10

y = 15(1) + 10

y = 25 + 10

y = $25

Therefore, in one hour (x=1), the cost will be: y = $25
