Alexandra is creating a food budget. Each day, her goal is to spend no more than $2 for breakfast, $8 for lunch, and $8 for dinner. Since there are about 30 days in a month, she estimates she will spend roughly $60 a month on food. Is that a good estimate?

Alexander estimate is not a good estimate

Step-by-step explanation:

Breakfast = $2

Lunch = $8

Dinner = $8

Total amount spent on food each month = (cost of breakfast × number of days) + (cost of lunch × number of days) + (cost of dinner × number of days)

= ($2 × 30) + ($8 × 30) + ($8 × 30)

= $(60 + 240 + 240)

= $540

Total cost estimate of food in a month = $540

Alexander estimate is not a good estimate

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

one set of data has more variation than the other. hope this !
