Given:
Cost of bracelet without charm - $85
cost of each charm - $15
Function notation: f(x) = 15x + 85
The price of the bracelet depends on the number of charms they will buy. x represents the number of charms they will buy.
The reasonable domain for this function is at least 1. They must buy at least 1 charm because they intend to buy their mom a silver charm bracelet.
If their budget is 250
250 = 15x + 85
250 - 85 = 15x
165 = 15x
165/15 = x
11 = x
They can buy at most 11 charms without going beyond their budget.
solve for x.
x+9y=18
Add -9y to both sides.
x+9y+−9y=18+−9y
x=−9y+18
solve for y.
x+9y=18
Add -x to both sides.
x+9y+−x=18+−x
9y=−x+18
Divide both sides by 9.
9y/9=−x+18/9
y=−1/9x+2
