Answer:
Step-by-step explanation:
case 1
cost of 20oz bottle of soda = $1.20
dividing both side by 20
cost of 20/20 oz bottle of soda = $1.20/20
cost of 1oz bottle of soda = $0.06
__________________________________________
Case 2
cost of 12oz bottle of soda = $0.85
dividing both side by 12
cost of 20/20 oz bottle of soda = $0.85/12
cost of 1oz bottle of soda = $0.07
Based on above calculation, we can see that first deal 20oz bottle of soda at costs $1.20 is better deal as per unit cost is $0.06 which is less than 12 oz can of soda costs $0.85 which is equivalent to $0.07 per unit cost
Answer:
y = √{(a - x)/2b}
Step-by-step explanation:
x=a-2by²
2by² = a - x
divide through by 2b
y² = (a - x)/2b
y = √{(a - x)/2b}
Answer:
30 is the wrong one because it is not a factor of 100
30 60 90 120
20 40 60 80 100
Step-by-step explanation:
Answer: Amount covered by financial aid=$3,585
Amount left that you have to pay =$1,195
Step-by-step explanation:
School cost for the term = $4780
Amount covered by financial aid = 3/4 of $4780
= 3/4 x 4780
Amount left that you have to pay=School cost for the term -Amount covered by financial aid
= $4,780 - $3,585
Amount left that you have to pay =$1,195
Looks like all real numbers except 1. It touch's all the y except 1 aka range
