Doughnuts cost $3.45 for a dozen at Store A, and cost $2.40 for 8

Mathematics

Answer:

store A is cheaper

Step-by-step explanation:

All right. If you divide Store A's numbers like so,

3.45 / 12, you'd get about 0.28, which is the average cost per one donut at store A.

For store B, if you divided,

2.40/8, you'd get 0.30, which is the average cost per one donut at store B, which means that store A is cheaper!

You discovered you can deduct medical expenses over 6% of your income. Your income is $42,000 and you had medical expenses of $5
iren2701 [21]

No portion of your medical expenses you can deduct

Step-by-step explanation:

You discovered you can deduct medical expenses over 6% of

your income

Your income is $42,000

You had medical expenses of $567

We need to find the portion of your medical expenses you can deduct

∵ Your income = $42,000

∵ You can deduct medical expenses over 6% of your income

- Find the 6% for your income

∵ 6% of the income = \frac{6}{100} × 42,000 = $2520

∴ 6% of your income is $2520

∵ You can deduct medical expenses over 6% of your income

∴ If your medical expenses greater than $2520, then you can

   deduct the value greater than it, but if your medical expenses

   smaller than $2520, then you can not deduct any value

∵ You had medical expenses of $567

∵ $567 < $2520

∴ There is no value you can deduct from your medical expenses

No portion of your medical expenses you can deduct

johns test grades in his science class are 82, 93, 75, and 89 what is his average? 1. (87.45) 2. (80.00) 3. (90.40) 4. (89.25) 5
inessss [21]

First you add all the numbers together. So you add 82+93+75+89 to get 339. Once you get that, you divide it by the amount of numbers there are. In this case, it's 4. 339 divided by 4 is 84.75.

HOPE THIS HELPS!!
