Answer:

=90.95

Step-by-step explanation:

Tax is found by taking the original price and multiplying by the tax rate

tax = 85 * 7%

tax = 85*.07

tax = 5.95

To find the final price, we add the tax to the original amount

final price = 85+5.95

=90.95

If set A has 4 elements and B has 3 elements then set n(AXB) is a) 12 b) 14 c) 24 d) 7

Karo-lina-s [1.5K]

Answer:

The correct option is a.

Step-by-step explanation:

Given information:

Number of elements in set A = 4

Number of elements in set B = 3

We need to find n(A × B). It means we have to find the number of elements in set A × B.

If P and Q are two sets with elements m and n respectively, then the number of element in the set P × Q is m × n.

$n(A\times B)=n(A)\times n(B)$

$n(A\times B)=4\times 3$

$n(A\times B)=12$

The value of n(A × B) is 12. Therefore the correct option is a.

Solve:<br> 2y + 5x=30<br> y = 3x + 4

mafiozo [28]

Replace the second equation y=3x+4 into the first one:
2(3x+4)+5x=30
Now solve for x:
6x+8+5x=30
11x=30-8
11x=22
x=22/11
x=2
Finally, replace x=2 into y=3x+4
y=3*2+4
y=6+4 = 10
So the anwer is x=2, y=10
