The solution for this question is simple. First we need to divide both numbers by 2 which will give us 10 and 7. This is the equation x^2/10^2 + y^2/7^2 = 1sqrt(100-49) = 7.14 (the answer do not have a perfect square root)
Foci are 14.28 units apart

There is a lot of unnecessary information here made to trip you up.

1% of $150 is $1,50. If we add that to her purchase, we get $151.50

Provided she pays during the grace period, she should only have to pay $151.50
