A jar contains nickels and dimes. There is a total of 200 coins in the jar and their value is $14.55. How many dimes are in the jar?

Plz show the steps

Answers

Answer:

There are total of 80 dimes in the jar cuz...

n + d = 200 = n = 200 - d

0.05n + 0.1d = $14.00

0.05(200 - d) + 0.1d = $14.00

10 - 0.05d + 0.1d = $14.00

10 + 0.05d = $14.00

-10 -10

0.05d = $4.00

0.05d / 0.05 = $4.00 / 0.05

d = 80

One market sells a 3-kilogram bag of tortillas for 45 pesos, and the second market sells 2 kilograms of tortillas for 22 pesos.

Which unit price is lower? / Would I subtract 2 kilo from 22 pesos?

Answers

Answer:

The second market is cheaper

Step-by-step explanation:

For the first market:

If the 3Kg = 45 pesos

then 1Kg = 15 pesos because you divide it by 3

In the same way for the second market:

2Kg = 22pesos

so 1Kg is 11 pesos as you divide it by 2.

Therefore the second market is cheaper as the unit price is lower.

The table shows the monthly fees for the checking accounts at two banks. Which statement is best supported by the information in the table?
A. The fee at Bank Y will be more than the fee at Bank Z only when a customer’s balance is more than $500.
B. The fee at Bank Y will always be more than the fee at Bank Z.
C. The fee at Bank Y will always be less than the fee at Bank Z.
D. The fee at Bank Y will be more than the fee at Bank Z only when the checking account balance is less than $500.

Answers

Answer:

A. The fee at Bank Y will be more than the fee at Bank Z only when a customer’s balance is more than $500.

The statement best supported by the information in the table is A. The fee at Bank Y will be more than the fee at Bank Z only when a customer’s balance is more than $500.

What is Percentage?

Percentage is defined as the parts of a number per fraction of 100.

Percentage is usually denoted by the symbol '%'.

Given in the table that,

Monthly fee for bank Y = 1% of checking account balance

Monthly fee for bank Z = $5

Suppose checking account balance = $500

Then,

Monthly fee for bank Y = 1% × 500 = 5

So, when the customer’s balance is $500, then fee at Bank Y is same as that of bank Z.

So, when the customer’s balance is more than $500, then fee at Bank Y is more than that of bank Z.

Hence the option is A.
