Step-by-step explanation:
210-x=50×2
or, 210-x=100
or, x=210-100
or, x=110
so,
z = 360-210-110
or, z = 40
Answer:
Marcus spent $6.36.
Step-by-step explanation:
First off, the fact that tax is included makes it easier for you, you don't need to worry about any multiplying!
Alright, so, he bought 2 candy bars for $0.79 EACH - that's 2 * $0.79 = $1.58.
Next, a drink for $1.49 and a bag of chips for $3.29. That's $1.49 + $3.29 = $4.78.
Now you add those two numbers up: $1.58 + $4.78 = $6.36.
Therefore, Marcus spent $6.36!
