Four sisters bought a present for their mother they received a 10% discount on the original price of the gift. After the dicount was taken, each sister paid $9.00. What was the orginal price of the gift?

$40.00

Step-by-step explanation:

the total price of the gift (after discount) is 9.00 * 4 = 36

the original price of gift can be found using this equation:

x - (x*0.10) = 36

x - 0.10x = 36

0.9x = 36

x=40

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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!
