Apples cost $3.60 for 3 lb. At that rate, how many pounds of apples can you buy for $8.40?

irinina [24]

Apples cost $3.60 for 3 pounds . The rate can be calculated as follows

$\begin{gathered} 3\text{ pounds = \$3.60} \\ 1\text{ pounds = ?} \\ \text{rate = }\frac{3.60}{3} \\ \text{rate}=\text{ \$1.2 per pound} \end{gathered}$

The amount of pounds you can buy for $8.40 can be computed below

$\begin{gathered} \text{rate}=\frac{8.40}{\text{pounds}} \\ 1.2=\frac{8.40}{\text{pounds}} \\ weight\text{ in pounds = }\frac{8.40}{1.2} \\ \text{weight in pounds = 7 Ib} \end{gathered}$

A pile of 55 coins, consisting of nickels and dimes, is worth $3.90. find the number of each.

xz_007 [3.2K]

<span>N + D = 55 coins (1) (N stands for nickels, 5N + 10D = 390 cents (2) D stands for dimes) Simplify (2) by canceling the factor 5 in both sides: N + 2D = 78 (3) Subtract eq(1) from eq(3). You will get D = 78 - 55 = 23. Answer. 23 dimes and 55-23 = 32 nickels. Check. 23*10 + 32*5 = 390 cents</span>
