Step-by-step explanation:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
So, 30% is 0.30, but since you are taking off 30%, you are going to have 70% of the price which is 0.70. The word "of" lets you know that you are going to multiply. So, what you do is 150•0.70=105. The discounted price is $105
Answer:
Rocco doesn't have enough money to buy the golf irons
Step-by-step explanation:
step 1
Find the rest of the money left in the savings account
using proportion
![\frac{\$48}{20\%}=\frac{x}{80\%}\\ \\x=48*80/20\\ \\x=\$192](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%2448%7D%7B20%5C%25%7D%3D%5Cfrac%7Bx%7D%7B80%5C%25%7D%5C%5C%20%5C%5Cx%3D48%2A80%2F20%5C%5C%20%5C%5Cx%3D%5C%24192)
step 2
we know that
The set of golf irons has an original price of $359
Applying 40% discount
100%-40%=60%=60/100=0.60
after the discount the price will be
![0.60(\$359)=\$215.4](https://tex.z-dn.net/?f=0.60%28%5C%24359%29%3D%5C%24215.4)
![\$215.4> \$192](https://tex.z-dn.net/?f=%5C%24215.4%3E%20%5C%24192)
therefore
Rocco doesn't have enough money to buy the golf irons
