Sherri got a new job as a teacher for the local school. her rent is going to be 40% of her income, she will save 10% each month, she plans to use 40% of her income on other fixed expenses, and will use 20% of her income to pay for flexible expenses such as going out with friends.

what mistake is sherri making?

40% of her income is going to rent.

she is making less than she is spending.

she is using 40% of her income on other fixed expenses.

she is saving 10% of her income each month.

The mistake she is making is that she is making less than she is spending

Step-by-step explanation:

Step 1: Determine her total income

Let her total income be x

Step 2: Determine amount of each expense

The amount of each expense can be expressed;

Amount of each expense=percentage of total expense×total income

a). Rent

percentage expense on rent=40%

total income=x

Amount of rent=(40/100)×x=0.4 x

b). Savings

percentage expense on savings=10%

Amount of savings=(10/100)×x=0.1 x

c). Fixed expenses

percentage fixed expense=40%

Amount of fixed expenses=(40/100)×x=0.4 x

d). Flexible expenses

percentage flexible expense=20%

Amount of flexible expenses=(20/100)×x=0.2 x

Step 3: Calculate total expenses

Total expenses=Amount of flexible expenses+fixed expenses+amount of savings+amount of rent

replacing;

Total expenses=(0.2 x+0.4 x+0.1 x+0.4 x)=1.1 x

Step 4: Get remaining amount of her income

Net income=(x-1.1 x)=-0.1 x

This means that her expenses exceed her income by -0.1 x. The mistake she is making is that she is making less than she is spending

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
