The price of gasoline on January 1 is g. The price of gasoline rose 15% above the January 1 price. Which expression
represents the new price of gasoline in terms of s?

15s
1.15s
.85s
85s

1.15s

Step-by-step explanation: The problem gives the original price as g. I don’t see how you can express the higher price in terms of s. It could be that the original price is s, not g. Maybe they made an error. I’m going to use s as the original price. In this case...

The new price is s plus 15% of s.

s + 15% of s=

= s + 0.15s

= 1.15s

Just remember when a variable does not have a coefficient, the coefficient is 1. So s = 1

And to turn a percentage into a decimal you need to move two places to the left. 15% = 0.15

no i do not : ( what is it?

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
