Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135
The answer is 8.

When you multiply each number by four the sum will be 28.
2 x 4 = 8
5 x 4 = 20
The total is 28.

Answer:
f(1) = 2
Step-by-step explanation:
<u>Step 1: Identify the function</u>
f(x) = x^2 + 2x^2 - x - 1
<u>Step 2: Simplify the function</u>
f(x) = 3x^2 - x - 1
<u>Step 3: Set x to 1 in the function</u>
f(1) = 3(1)^2 - (1) - 1
f(1) = 3*1 - 1 - 1
f(1) = 3 - 1 - 1
f(1) = 2
Answer: f(1) = 2
