Question

alissa has $75 worth of bird seed, which she will put out into small bags. she will sell each bag for $7. what is the greatest number of bags she must sell in order to have no less than $10 worth of bird seed left over?

Answer 1

so basically
x=number of bags
75-7 times x>10
solve fr x
add 7x to both sides
75>10+7x
subtract 10
65>7x
divide both sides by 7
9.2>x
the nearest whole number is 9 because we don't want to go over and we can't sell 9.2 bags

answer is 9 bags
