Gianna was awarded $37,000 for winning her school's engineering competition. She decided to invest her winnings in two different accounts: one earning 4% interest and the other earning 8% interest. If she collects $2480 of annual interest income, how much did she invest in each account?

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

or

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
