Last weekend, raptor club members spotted 160 hawks. this weekend they saw 70% as many as they saw last weekend. how many hawks did they see this weekend?

Astudent must have an average on five test that is greater than it equal to 80% but less than 90% to receive a final grade of b. devon's greades on the first four test were 78% 62% 91% and 80% what range if grades on the fifth test would give him a b in the course? ( assuming the highest grade is 100%)
