small frames ($8): s
large frames ($15): L
Cost: 8s + 15L = 239 ⇒ 1(8s + 15L = 239) ⇒ 8s + 15L = 239
Quantity: s + L = 22 ⇒ -8( s + L = 22) ⇒ <u> -8s -8 L = -176 </u>
7L = 63
L = 9
Quantity: s + L = 22 ⇒ s + (9) = 22 ⇒ s = 13
Answer: 13 small frames, 9 Large frames
<u>Answer</u>
<span>(D) 14.2x0.784
<u>Explanation</u>
We do not have to multiply these number to tell the number of decimal places of the product.
The product of a set of number will have the sum of the decimal places of the factors. For example, in
</span>(A) 5.3478x6.4214 ⇒ 4+4= 8 decimal places
(B) 6.4x3.82 ⇒1+2= 3 decimal places<span>
(C) 521x3.82 </span>⇒ 0+2 = 2 decimal places. <span>
(D) 14.2x0.784</span> = 1+3= 4 decimal places.
the correct answer is (D) 14.2x0.784
