Answer:
416.01
Step-by-step explanation:
49% is the same as 0.49
0.49 × 849 is 416.01
C = 15x + 50
let c be $125 since c represents the cost
15x + 50 = 125
15x = 125 - 50
15x = $75
x = 75 ÷ 15
x = 5
Answer:

Step-by-step explanation:
Given that,
A rectangular prism is 4 inches long, 3 inches wide and 8 inches tall.
We need to find the volume of the rectangular prism. The formula for the volume of prism is given by :

So, the volume of the prism is equal to
.
Let us denote the number of tiles by

.
In the first store, if Darin bought

tiles, he would need to spend:

(measured in $)
In the second store, if Darin bought

tiles, he would need to spend:

(measured in $)
For the cost to be the same at both stores, it means (measured in $)

Moving

over to the left hand side and changing signs:

tiles
Let's check. If he buys 60 tiles in the first store, he spends:
$0.79×60 + $24 = $47.40 + $24 = $71.40
If he buys 60 tiles in the second store, he spends:
$1.19×60 = $71.40
∴
Darin needs to buy 60 tiles for the cost to be the same at both stores.
