Answer:
76
Step-by-step explanation:
First we simplify the expression to make it easier :
y + 29y -23y = 7y
3y× y = 3y²
3y² + 7y
Now we substitute the y value given and simplify to find our answer:
3(4)² + 7(4) =
3(16) + 28 =
48 + 28 = 76
Our final answer is 76

Answer:
I BELIEVE YOUR ANSWERS ARE BETWEEN C AND A
Step-by-step explanation:
I don't know this but I will say C.
Cost of the spa treatment = $42
Percentage of sales tax = 6%
Percentage of tips = 20%
Normally the tips amount is calculated before adding sales tax.
Then
Amount of tips given = (20/100) * 42
= (1/5) * 42
= 8.40 dollars
Amount of sales tax taken = (6/100) * 42
= 252/100
= 2.52 dollars
Then
The total amount spent for spa treatment = (42 + 8.40 + 2.52) dollars
= 52.92 dollars
So we can see that $52.92 has been spent in total for spa treatment and this amount includes a sales tax of $2.52 and a tip of $8.40.
