Step-by-step explanation:
Answer:
$5750
Step-by-step explanation:
For simple interest,
I = prt
115 = p × 0.03 × 8/12
p = 5750
So you know each french fry equals 25 calories. So amount of calories per french fry = 25f
Similarly we know each chicken wing has 100 calories so amount per chicken wing = 100c
So total calories = 25f+100c
Now we know that we want the total to be less than 500
Therefore the inequality should look like this
25f+100c<500
Answer:
4.56
Step-by-step explanation:
After this equation is simplified, it is solved the way any 1-step linear equation is solved.
__
1.4t -0.4(t -3.1) = 5.8 . . . . . . given
1.4t -0.4t +1.24 = 5.8 . . . . . eliminate parentheses
t +1.24 = 5.8 . . . . . . . . . collect terms (now you have a 1-step equation)
t = 4.56 . . . . . . . . . .subtract 1.24
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
