For numbers 10-13, write an equation that represents the proportional relationship between total cost (c) and the number of items a person might buy (x), using the store that offers the best price. where would you buy each item? keep in mind that an equation allows someone to calculate the total cost of a particular grocery item no matter how many of that item is purchased. hint: the cost equation should have the variable ‘c’ and ‘x’ in it. 10a. which store has the best priced smooth cola 12-pack? * 1 point a) store 1 b) store 2

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
