Leila is buying a dinosaur model. The price of the model is z dollars, and she also has to pay a 7% tax. Which of the following expressions could represent how much Leila pays in total for the model?

T=z(0.07)+z

Step-by-step explanation:

Dat right der

i pretty sure it is

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
