Mrs. Miller has only $42.50 to spend at walmart. She buys a shirt that costs $19, including tax. She wants to buy some bracelets for 4.50 each, including tax. Write an equation to determine x, the maximum number of bracelets Mrs. Miller can buy.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
