$4750 invested at 10% p.a compounded semiannually for 10 years, calculate the interest

alexgriva [62]

<h3>Answer: $7,853.16</h3>

Work Shown:

A = P*(1+r/n)^(n*t)

A = 4750*(1+0.10/2)^(2*10)

A = 12,603.164099436

A = 12,603.16

That represents the account balance after 10 years. To find the interest only, subtract off the deposit amount.

interest = A-P = 12,603.16 - 4,750 = 7,853.16

Price-club sells a 12-ounce package of spaghetti noodles for $3.44 and Shop Mart sells a 2-pound box of spaghetti noodles for $8

Eva8 [605]

The unit price per ounce at Price club is $0.29 and the unit price per ounce at Shop Mart is $0.26

Step-by-step explanation:

Price of 12 ounce package at Price Club = $3.44

Unit rate per ounce = $\frac{Price\ of\ package}{Weight\ of\ package}$

Unit rate per ounce = $\frac{3.44}{12} = \$0.29$

Price of 2 pound box at Shop Mart= $8.35

1 pound = 16 ounce

2 pound = 16*2 = 32 ounces

Unit rate per ounce = $\frac{Price\ of\ package}{Weight\ of\ package}$

Unit rate per ounce = $\frac{8.35}{32} = \$0.26$

The unit price per ounce at Price club is $0.29 and the unit price per ounce at Shop Mart is $0.26
