To figure out the average of Michael and Melissa we must add up all their test scores and divide the by 7; which is the number of tests they took.
Michael:
(80+76+73+70+40+25+10)/7
Melissa:
(88+83+75+70+60+65+62)/7
Michael's average is 53.4
Melissa's average is 71.9
So Melissa is earning a C in Latin.
1 persona pagaba 341 por ida y 298 por venido lo que significa que 1 persona paga en total= 639
si son 16 seria= 639*16=10224 en total
B + 1.1 = -11
Subtract 1.1 from both sides to get b.
So, b = -12.1
