Hello,

Answer C

y=2x-3.5==>2x-7=3.5 (1)
x-2y=-14 (2)

(1)-2*(2)==>3y=28+3.5 ==>y=31.5/3==>y=10.5
x=-14+2*10.5==>x=7
sol={(7,10.5)}

John took all his money from his savings account. He spent $110 on a radio and 4/11 of what was left on presents for his friend

svp [43]

Answer:

$1210

Step-by-step explanation:

Let x be total amount

First John spent $110 on a radio and 4/11 of what was left on presents for his friends so he was left with

$\frac{7}{11}(x-110)=\frac{7}{11}x-70$

Then he put 2/5 of his remaining money into a checking account

$\frac{3}{5}\left(\frac{7}{11}x-70\right)$

Rest he donated to charity

$420=\frac{3}{5}\left(\frac{7}{11}x-70\right)\\\Rightarrow \left(\frac{7}{11}x-70\right)=\frac{2100}{3}\\\Rightarrow \frac{7}{11}x-70=700\\\Rightarrow \frac{7}{11}x=770\\\Rightarrow x=1210$

Hence total amount of money John originally had was $1210

Mr. Smith had 33 dozen cans. He sold 340 of them at 15$ each. He sold the remaining cans at a discount of 20% each. How much mon

iren2701 [21]

Answer:

Mr. Smith collects $5748 from selling the can.

Step-by-step explanation:

Given total number of cans = $33\times12=396$

Selling price of one can = $15.

$\therefore \textrm{Selling price of 340 cans} = \textrm {selling price of one can} \times \textrm {number of cans}=15\times340=\$5100$

Now remaining number of cans = total number of cans - sold number of cans = $396-340=54$

For remaining number of cans he gives a discount of 20% each,

∴ Selling price of one can = $15-\frac{15\times20}{100}=15-3=12$

∴ Selling price of 54 cans = $\textrm{selling price of one can} \times \textrm{number of cans}=12\times54=\$648$

So total money he earns = $\$5100+\$648= \$5748$ .

Thus Mr. Smith earns $5748 by selling the cans.
