Your tennis team is having a fundraiser. You are goint to sell sun visors and baseball caps to help? write an equation for the total amount you raide.
Part 2: Your team raises $4480, give 3 possible combinations of the sun visors and baseball caps that could have been sold if hte price of the sun visor was $3 and the baseball cap was $7. Please show step by step process.
thank you

T = vx + cy
where v is the profit from visors, x is the number of visors, c is the profit from caps, and y is the number of caps
3x + 7y = 4480
y = -0.4286x + 640
This is the equation for the straight line. Any two nonnegative integers x,y will be valid.
A few (x,y) are (0,640), (7, 637), (14, 634) and so on...

Part1:
if x=number of sun visors and y=number of caps
Then, your total amount would be:
a*x + b*y = c
and
a - price of sun visors
b- price of caps
c- total amount
Part2
3*x + 7*y = 4480
If you sold 100 caps, then you got
3x+700 = 4480
3x=3780
x=1260
So, you sold 1260 sun visors and 100 caps.
If you sold 1 caps, then
3x+7=4480
3x=4473
x=1491
So, you sold 1 cap and 1491 sun visors.
Or you can choose to give a random number for the number of sun visors sold
example: if you sold 7 sun visors then
21+7y=4480
7y=4459
y=637
So, you sold 7 sun visors and 637 caps
