Answer:
C) 20, 4
Step-by-step explanation:
X = 5y
2x + 5y = 60
substitute in 5y for x: 2(5y) + 5y = 60
10y + 5y = 60
15y = 60
y = 4
x = 5y
x = 5(4) = 20
The unit rate is found by dividing the amount earned by the number of hours worked. So
unit rate = amount earned / number of hours worked = 51 / 6 = $8.5 / hour
Answer: 87 c
Step-by-step explanation:
To evaluate the cost per juice box, we must first factor out the bag of apples from the equation. So we will disregard the price of the apples from the total price and also disregard the existence of the apples altogether.
Our new subtotal is $15.66 for eighteen juiceboxes. To find the cost for one juicebox, we divide the price & the # of juiceboxes by 18.
15.66÷18=0.87, therefore each juicebox is 87 cents.
Divide both sides by 2
a-c=2a
minus a fromboth sides
-c=a
