Montano1993 [528]
Let x be the total weekly sales.

His salary is $300/week + 1.8% (x), if he wants to earn $570, then:

300 + 1.8%(x) = 570
1.8%(x) = 270
0.018 (x) = 270

Evaluate 8a-1+0.5b8a−1+0.5b8, a, minus, 1, plus, 0, point, 5, b when a=\dfrac14a=
professor190 [17]

Answer: 6

Step-by-step explanation:

Given the following expression:

8a-1+0.5b

You need to substitute the given values of "a" and "b" into the expression. Notice that these values are:

a=\frac{1}{4}\\\\b=10

Then;

 8a-1+0.5b=8(\frac{1}{4})-1+0.5(10)

Now you must solve the multiplications:

=\frac{8}{4}-1+5=2-1+5

The final step is to add the numbers. Therefore, you get the following answer:

=6
