Answer:
The better buy is 16 cards for $12.20 because
Step-by-step explanation:
You need to find the individual price for each card in the packet. So first lets do 16 cards for $12.20, you divide $12.20 by 16 to get the price of one card. 12.2/16=0.7625, or about $0.76. Next we do $10.90 divided by 14, 10.9/14=0.7785, or about $0.78, which means 16 cards for $12.20 is the better buy!
Let's convert this fraction to an equal fraction which holds a denominator of 100, since it is a power of 10.
Since the denominator can be multiplied by 5 to achieve 100, we can multiply the entire fraction by 5 to create an equivalent fraction that has a denominator of 100:
17/20 = (17*5)/(20*5) = 85/100
To obtain a decimal from this fraction, take the numerator and move its decimal one place to the left for every 0 in the denominator. Since our denominator has two zeros, we will need to move the decimal place on the 85 two places to the left.
This gives us an answer of .85, which can also be expressed as 0.85.
Answer:
y=10
Step-by-step explanation:
10x6=60
It is given that Total Calories in the meal = 333
Calories per Grilled Chicken Strip = 110
# of Grilled Chicken Strips = x
Calories per Carrot = 29
# of Carrots = y
So the above information can be represented as:
Total Calories = (Calories per Grilled Chicken Strip × Number of Chicken Strips) + (Calories per Carrot × Number of Carrots)
Substituting the values in the above equation.
⇒ 333 = 110 × x + 29 × y
⇒ 110 × x + 29 × y = 333. This equation is in standard form, as an equation in standard form has the format Ax + By = C.
Out of the below options
(A) 110y = –29x + 333
(B) 29x + 110y = 333
(C) 29y = –110x + 333
(D) 110x + 29y = 333
So the standard form of equation matches with option (D), and hence the correct answer is 110x + 29y = 333
