A_1 = A_2

7(x + 7) = 8(x + 5)

A suit originally costing $240 is on sale for 25% off the original price. Sales tax is 7.5%. What is the final cost of the suit?
Finger [1]
$193.50

start by multiplying 240 by .25 (25%) to find out how much is 25% of 240. this equals 60.
then, subtract $60 from $240. equals 180.
next, to add the sales tax, multiply 180 by 0.075 (7.5%) this is $13.50.
lastly, add the tax, which is $13.50, to the suit's sale price, which is $180.
180+13.5= $193.50

f(-2)=-(-2)²+1=-4+1=-3
f(0)=-(0)²+1=0+1=1
f(2)=-(2)²+1=-4+1=-3

How many milliliters of 0.30%. sugar solution must you add to 75 mL of 4% sugar solution to get a 0.50% sugar solution? show you
LekaFEV [45]
<span>We have 75 mL of 4% sugar solution.
We have to add a 30% sugar </span><span>solution to make a 50% </span><span>sugar solution.
75 * .04 + .30x = .50 * (75 +x)
3 + .30x = 37.5 +.50x
I can't get the equation to solve.
Did you type it correctly? For one thing, you have the percentages typed as .30 % and 4%.  Are the decimal places in the correct positions?

Also, no matter how much 30% sugar solution you add, it will NEVER increase to 50%.
