You paid $4.76 total for 7 notebooks. To figure out how much each individual notebook cost, you divide the total cost by the number of things you bought, so
Cost of One Notebook = Total Cost of Notebooks / Number of Notebooks = $4.76 / 7 = $0.68
This is the unit rate.
To buy three notebooks, you just calculate the total cost of three notebooks at this price point, so
Cost of Three Notebooks = Cost of One Notebook * 3 Notebo0ks = $0.68 * 3 = $2.04
Answer:
22 Hours
Step-by-step explanation:
Divide 8 by 176, 176/8 = 22
Part A:
x - total number of liters ( milk + water )
0.2 x + 1 = x
Part B :
0.2 x + 1 = x
0.8 x = 1
x = 1 : 0.8 = 1.25 lit.
Milk:
1.25 x 0.2 = 0.25 lit.
5 because they would most likely want a high amount of coins it's common sense. But if they were very strategic they'd probably also pick 3 but most of the time the value expected would be 5.
No it doesn't work for both therefore can't be a solution
