Answer:
$28.20
Step-by-step explanation:
Let's set up an equation.
Let b be the cost of a bumper sticker.
Since the sum of the prices of 11 bumper stickers total up to $10.34, we can set up an equation!
11b = 10.34
Dividing by 11 on both sides,
b = 0.94
Plugging in b into 30b,
30(0.94)
We get
$28.20
Answer:
$28.20
Step-by-step explanation:
First, find out how much each bumper sticker costs.
Assuming that the cost of each bumper sticker is the same, the following equation represents how much one bumper sticker costs
11x = 10.34
Solve for x [divide both sides by 11]
x = 0.94
So, one bumper sticker costs $0.94
Now, find out how many 30 bumper sticker costs.
The following equation represents how much 30 stickers cost.
30x = y
X represents the cost of one sticker and y represents the cost of 30 stickers.
We already know the value of x [one bumper sticker's cost] which is $0.94, so subsitute that in for x.
30[0.94] = y
28.2 = y
So, 30 bumper stickers cost $28.20.
I hope this helps!
