The regular price of a calculator is $15.40 it goes on sale for 30% of the regular price. what is the amount of saving on the calculator ?

You wanna multiply the original price by the decimal of the percentage, 15.40*0.3=4.62

$4.62 is the amount your saving, if you want to know how much money your paying for the product, all  you have to do is subtract the number you got from the original price. Hope this helps ya'.

the answer is d. (1.2, -4.7) on edgn

hope this !

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
