Heather spent part of her Labor Day getting the last of her school supplies. She purchased the following:

one box of 216 tissues for $1.29
one calculator for $7.99
five 3-subject notebooks for $.69 each
one 10-pack of blue pens for $.99
one dozen No. 2 pencils for $1.09
one 5-pack of colored pens for $2.49
two 150-sheet packs of loose-leaf paper for $.99 each
one 3-ring binder for $1.99
one glue stick for $.44
Help Heather calculate her total bill, keeping in mind that she must pay 5% sales tax.

Your short answer should state the total using a complete sentence. Be sure your explanation includes how to calculate 5% tax.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
