Answer:
4
Step-by-step explanation:
She can use a dime and a quarter to buy one package. With 3 dimes and more than 3 quarters, she can buy 3 packages this way.
She can use 2 nickels and a quarter to buy one package. With 2 nickels and the 2 remaining quarters, she can buy 1 package this way.
Mae-Ying can buy 4 packages, and will have 1 quarter left over.
_____
You can add up her money and divide by 35¢ to find the number of packages. Doing that, you get ...
5·0.25 +3·0.10 +2·0.05 = 1.25 +0.30 +0.10 = 1.65
Then 1.65/0.35 ≈ 4.71, so Mae-Ying can buy 4 packages with the money she has.
Let's say the smaller number is x. Then, we can represent the larger number as x + 1. The +1 means that it's both larger, because adding makes a number larger, and consecutive, because it's 1 greater or less.
Then, we can write an equation. The sum of the two numbers is x + (x + 1), and it's equal to -165.
x + (x + 1) = -165
2x + 1 = -165
2x = -166
x = -83
Since x = -83, the smaller number is -83.
