A Fourth of July promotion included a $5.00 mail-in rebate for the purchase of a picnic cooler and a store coupon for 50¢ off the price of a case of 24 cans of soda.
For the company picnic, Carl Rhiel purchased a 48-quart cooler for $32.99 and a
case of soda for $6.99.What did it cost him after the rebate if an envelope costs
15¢ and a stamp costs 39¢?

∞ this is your sign

answer: it's d

step-by-step explanation:

the correct answers i think are b. and d.

give me brainliest if it is correct!

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
