a. In the news, you hear “tuition is expected to increase by 7% next year.” If tuition this year was $1200 per quarter, what will it be next year?

b. The value of a car dropped from $7400 to $6800 over the last year. What percent decrease is this?

Respuesta :

Answer: $1284 per quarter

Step-by-step explanation: each quarter this is $1200 meaning a quarter is 4 month so multiply a quarter by 3 which makes it 12 months that makes of a year. Knowing is 3 quarter in a year, multiply 3*$1200= $3600 is the total tuition for a year

If the increase for the year is 7%

7/100* 3600= $252 which is the increase amount

Add it to the previous year $3600+$252=$3852 for the next year

However we want to know it quarterly you divide the amount by 3

$3852/3 = $1284 per quarter of the next year

1200 x 4 is 4800. 7% = 336
4800+336= 5136
