(Emergency) Isaac owes $474.43 on his credit card. He returns two items, one for $48.90 and the other for $45.38. Then he makes purchases of $38.39 and $31.03. What is the new balance on the card?

The new balance on his card is $-449.57

Step-by-step explanation:

He starts by owing $474.43 which is -474.43

First, he returns $48.90 and $45.38 which means that we are going to add 48.9 and 45.38 to -474.43

, he returns $48.90 and $45.38 which means that we are going to add 48.9 and 45.38 to -474.43-474.43 + 48.9 + 45.38 = -380.15

, he returns $48.90 and $45.38 which means that we are going to add 48.9 and 45.38 to -474.43-474.43 + 48.9 + 45.38 = -380.15Now he owes the bank $380.15

Next, he purchased 2 more items for $38.39 and $31.03 which indicates -380.15 - 38.39 - 31.03.

-380.15 - 38.39 - 31.03 = -449.57

Therefore he owes the bank $449.57 now

Please refer to the attached diagram. The given circle is the blue circle centered at A and the given exterior point is C.

Draw line segment ACUsing the same radius for each, which radius is longer than half the length of AC, draw the orange arcs centered at A and C so that they intersect at points D and E.Draw the yellow line DE. Designate the point where it intersects AC as point F. This is the midpoint of AC.Using F as the center, draw green circle F with radius FA (or FC). Designate the points where circle F intersects circle A as points G and H.Your tangent lines are CG and CH (shown in lavender).
