Step-by-step explanation:
To find the cost of the tip, we need to find 120% of 39.50.
120% = 100% (order) + 20% (tip)
Let's use fractions. 39.50 can be put over 1, and 120 can be put over 100.
<u>Equation:</u>

The total cost of the food is $47.40.
Answer:
$22.50
Step-by-step explanation:
if 3 bags of cat food = 13.50, divide 13.5 by 3 to get the cost of one bag, which is $4.50.
since hes getting 5, we can use 13.50 once and then the price of one bag (4.5) twice for the other two.
so that would be 13.5 + 4.5 + 4.5 = $22.50
hope this helped :)
First thing to do is set up your equation:
45/x = 20/100
Cross multiply
4500 = 20x
And divide by 20
Answer: 225 people were surveyed
D = 15(t + 1)
Explanation:
It would be t + 1 rather than t - 1 because he has one *more* hour compared to the other riders.
The reason why t + 1 is in parentheses is because when solving, you'd have to first add instead of multiply.
Answer: 50a+2
Step-by-step explanation:
1. Simplify 5a5a\5a5a to 1.
1+5×10a+10
2.Simplify 5×10a to 50a.
1+50a+10
3.Cancel 10.
1+50a+1
4. Collect like terms.
50a+(1+1)
5. Simplify.
50a+2
