Answer:
<u>$13.59</u>
Step-by-step explanation:
((2 1/2)lbs grapes)*($2.64/lbs grapes) + ((2 3/4)lbs strawberries)*($3.09 lbs strawberries) = total cost before discount.
Total Cost = (2.5)*(2.64) + (2.75)*(3.09)
Total Cost = 15.0975 round to $15.10
10% discount = (1 - 0.10) = 0.90
(0.90)*($15.10) = <u>$13.59</u>
Answer:
(0,3)
Step-by-step explanation:
7x-2y=-6
8x+y=3
Multiply the second equation by 2 so we can eliminate y
2(8x+2y) = 2*3
16x+2y=6
Add the first equation to the modified second equation
7x-2y=-6
16x+2y=6
--------------------
23x = 0
Divide by 23
23x/23 = 0/23
x =0
Now we need to find y
8x+y = 3
0+y =3
y=3

Answer:
= 3oz
Step-by-step explanation:
v = 20mm ×150mm ×2mm = 6000 mm^3
so, the weight is
6000 mm^3 × 0 .0005oz/1mm^3 = 3oz
