The average adult working male spends approximately $60 per week on a moderate cost healthy diet plan. the average cost for 3 fast food meals per day is approximately $20. on average, what can you save per week with the healthy diet plan?

On average,  you can save $ 80 per week with the healthy diet plan.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Weekly cost on a moderate cost healthy diet plan = $ 60

Average cost  for 3 fast food meals per day = $20

2. On average, what can you save per week with the healthy diet plan?

Let's calculate the amount of savings, this way:

Savings = 7 * Average cost  for 3 fast food meals per day - Weekly cost on a moderate cost healthy diet plan

Savings = 7 * 20 - 60

Savings = 140 - 60 = 80

On average,  you can save $ 80 per week with the healthy diet plan.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

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.
