A jar of quarters and dimes has total value of $20.70. The jar has 10 more quarters than dimes. To find the numbers of quarters

lakkis [162]

There are 62 quarters and 52 dimes in the jar.

Step-by-step explanation:

Given,

Worth of jar coins = $20.70 = 20.70*100 = 2070 cents

1 Quarter = 25 cents

1 Dime = 10 cents

Let,

Number of quarters = x

Number of dimes = y

According to given statement;

25x+10y=2070 Eqn 1

x=y+10 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$25(y+10)+10y=2070\\25y+250+10y=2070\\35y=2070-250\\35y=1820\\$

Dividing both sides by 35

$\frac{35y}{35}=\frac{1820}{35}\\y=52$

Putting y=52 in Eqn 2

$x=52+10\\x=62$

There are 62 quarters and 52 dimes in the jar.

Miguel earns 2,456.75 every month he also earns an extra 4.75 every time he sells a new gym membership last month Miguel sold 32

zalisa [80]

Answer: Total amount of money earned last month = $2608.75

Step-by-step explanation:

Miguel earns 2,456.75 every month. This is his constant pay for the month. He also earns an extra 4.75 every time he sells a new gym membership.

Last month, Miguel sold 32 new gym membership. This means that the extra money that he earned for last month will be the number of new gym membership sold times the amount her earns per new gym membership sold. It becomes

32 × 4.75 = 152

Total amount of money earned last month will be sum of his monthly salary + the extra earned. It becomes

2456.75 + 152 = $2608.75
