Answer:
if you mean the unit price is per lb
2.49
Step-by-step explanation:
9.96/4
Consecutive integers are 1 apart
so the 4 are
x, x+1,x+2,x+3
they add to 8
x+x+1+x+2+x+3=8
4x+6=8
minus 6 both sides
4x=2
divide both sides by 4
x=1/2
false, 1/2 is not an integer
if it was adding to 18, then the integers would be 3,4,5,6
but we can't find consecutive integers that add to 8
The answer would be y=4x-18.
1) online has the lower unit price
27.25 / 5 = 5.45
32.16 / 6 = 5.3583333.... rounded it would be
5.35
2) The cost of 7 pounds would be 103.18
73.70 / 5 = 14.74 (cost of one pound)
14.74 x 7 = 103.18
3) The scarf in October costed more
13.35 / 3 = 4.45 (one scarf)
22.65 / 5 = 4.53
hope this helps
