The correct answer would be D and I'll explain why. The table is giving you coordinates that are supposed to be on the coordinate plane. When reading coordinates and placing them on a plane x goes before y. Therefore the first point would be (3, -4). Because 3 is x, you need to go along the x-axis until you find a positive 3 - which would be to your right. Next is -4 on the y-axis, which would be the vertical line. The positives will always be above and to the right. Since it's a negative number, you go down until you find a negative 4. Now that you've found where 3 and -4 is, see where they intersect and that's where the point will be. Now, you can continue like this for the rest of the coordinates.

Last year, sales at Company X were 10% greater in February than in January, 15% less in March than in Feb, 20% greater in April

Svetlanka [38]

Answer:

d. May

Step-by-step explanation:

Working through the chain, we have ...

Feb = 1.10×Jan

Mar = 0.85×Feb = 0.935×Jan

Apr = 1.20×Mar = 1.122×Jan

May = 0.90×Apr = 1.0098×Jan

Jun = 1.05×May = 1.06029×Jan

The multiplier that is closest to 1 is 1.0098, so May has sales closest to January.

The percentage increase or decrease can be converted to a multiplier by adding it to 1. If p% is the percentage change, then adding it to an original value looks like ...

original + p% × original = original × (1 +p%) . . . . . . . distributive property

And p% translates to a decimal number by replacing % with /100 or ×0.01.

10% increase: original × (1 + 10/100) = original × 1.10

15% decrease: original × (1 - 15/100) = original × 0.85
