The marching band sold gift wrap priced at $4.00 per roll for solid colors and $6.00 per roll for print patterns. if they sold 480 rolls of gift wrap and collected $2340,the how many rolls of each type of gift wrap did they sell

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210

Step-by-step explanation:

Let

x ---> the number of gift wrap rolls for solid colors sold

y ---> the number of gift wrap rolls for sprint patterns sold

we know that

----> ----> equation A

----> equation B

Solve the system by substitution

substitute equation A in equation B

solve for y

Find the value of x

---->

therefore

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
