Terri needs $250 to buy Christmas gifts this year. She has $75 saved already and she is saving $45 each week. Find the slope for this problem

Respuesta :

$250 = $75 + ?
45 × 3 = 135
135 + 75 = 210
210 + 45 = 255
? = 180
$75 + ( 45 × 4 ) = 255
so she could save up 4 weeks worth of money plus the other 75 with an extra $5 to spend or save for something
