Answer:
-17
Step-by-step explanation:
First, you have to add up the cost of each meal and drink:
12.50 + 12.50 + 1.50 + 1.50 = 28
$28 is the cost before the tip. Now multiple 28 by .18 to find the tip:
28 x .18 = 5.04
The tip was $5.04. Add the 28 and the 5.04 to get the total cost:
28 + 5.04 = 33.04
ANSWER:
The total cost was $33.04
Answer:
A. 175 m
B. 20 cm
Step-by-step explanation:
x = 175 m
x = 20 cm
For a problem like this, you'll want to break it down ...
Total cost = $19.60.
Cost of beads = $12.80.
Cost of pendant = ?
We know that there are 4 necklaces. Each necklace has one pendant, so we have 5 pendants total. Therefore, your solution should look something like this ...
Total cost = Cost of beads - cost of pendant
$19.60 = 12.80 - 4x <- x is the variable representing the price for a single pendant.
6.80 = 4x <- Subtract 12.80 from both sides.
x = 1.70 <- Divide both sides by 4, and find your final answer.
x = 1.70; therfore, each pendant costs $1.70.
$49,400. If you multiply the income (38,000) by the salary increase (3%=0.3), then you get 49,400. Good Luck!
