Answer:
29 multiple-choice questions
and 6 word problem questions
Step-by-step explanation:
let x be the number of multiple-choice questions
and y be the number of word problem questions
then:
x+y=35
2x+7y=100
x=35–y
2(35–y)+7y=100
70–2y+7y=100
70+5y=100
5y=100–70
y=30/5=6
since x+y=35
then x+6=35
then x=35–6=29
