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:
x = 3
y = -2
Step-by-step explanation:
x - 2y = 7
y = -x + 1
x - 2y = 7
x - 2 ( -x + 1 ) = 7
3x - 2 = 7
3x = 9
x = 3
y = -x + 1
y = -3 + 1
y = -2
