Lin’s father is paying for a $40 meal he has a 25% off coupon for the meal after the discounts 8% sales tax is applied what does lynn’s father pay for the meal!

32.4 $

Step-by-step explanation:

25% off means he is paying 75% of the original price

Original price = 100%

75%=0.75=3/4

3/4 of 40 is 30

Apply 8% tax on amount of 30$ and add calculated value to 30$.

OR: you can think of 30 $ as  100%. You have to add 8% tax--. now you have 108%

108%=1.08

1.08*30=32.4  

5050

hope this !

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
