Jason earned $600 over the summer by babysitting. It took him 10 shopping trips to purchase the things he needed for the new school year – school supplies, new clothes and soccer gear. Each trip he spent $10 more than on the previous trip. After the 10th trip, he had spent all his summer earnings.
How much did Jason spend on the first shopping trip?

$15 :
x= amount spent on 1st trip
x+x+10+x+20+x+30+x+40+x+50+x+60+x+70+x+80+x+90= 600
10x + 450 = 600 (subtract 450 from both sides)
10x = 150 (divide by ten on each side)
x= 15
He spent $15 on his first shopping trip
