You have 20 quarters and then find 40% more and then spend 75% how much money do you have left

kirza4 [7]

You have $1.75 left

Step-by-step explanation:

Given,

Number of quarters already have = 20

Percent of quarters found = 40% of already have

Number of quarters found = $\frac{40}{100}*20$

Number of quarters found = $\frac{800}{100}$

Number of quarters found = 8

New total = 20+8 = 28 quarters

Percent of quarters spent = 75%

Number of quarters spent = $\frac{75}{100}*28$

Number of quarters spent = $\frac{2100}{100}$

Number of quarters spent = 21

Quarters left = 28-21 = 7

1 quarter = 25 cents

7 quarters = 25*7 = 175 cents

$1 = 100 cents

175 cents = $\frac{175}{100}=\$1.75$

You have $1.75 left

ZanzabumX [31]

The registration for new members of a gym is $ 1.
The gym payment per day is $ 1.
The equation that models this problem is:
y = x + 1
Where,
x: is the number of training days
y: it is the total payment
The intersection with the y axis (1) represents the cost of the inscription.
The slope of the line (1) represents the daily payment.
