you are making curtains by alternating strips of solid colored fabric and patterned fabric. the solid colored fabric costs 99¢ p

weeeeeb [17]

Hello,

to find the total cost (c) of the colored strips we have to multiply the number of strips (n) by the cost of each color strip (99¢), that as an algebraic function is:

$\boxed{c= n*99}$ [¢]

Now, if we use 3 solid color strips, that means that we use 4 patterned strips, so:

$Cost=3*0.99+4*1.25 \\ \boxed{Cost= 7.97}$

Answer: c=n*99 and Cost per curtain= $7.97

if your car gets 28 miles per gallon, how much does it cost to drive 310 miles when gasoline cost $3.50 per gallon?

Butoxors [25]

Hi,

Work:

$28miles = 1gallon$

To find the cost of gallons spend for 310 miles you need to first find the amount of gallons consumed on 310 miles path.

$310 \div 28 = 11.07gallons$

If each costs 3.5$ you need to multiply gallons with money.

$3.5 \times 11.07 = 38.745$

You would spend 38.745$ to drive 310 miles.

Hope this helps.
