Company A:
c = 40 + 2s
Company B:
c = 20 + 4s
Equal costs => 40 + 2s = 20 +4s => 4s - 2s = 40 - 20 => 2s = 20 => s = 20/2
=> s = 10
And c = 20 + 4s = 20 + 4(10) = 20 + 40 = 60

Then, it costs $2120 to order 1000 pens and 2000 notebooks.
Step-by-step explanation:
The Students' Union needs to order 1000 pens and 2000 notebooks. The price per pen when buying 1000 of them is 60c. The price per notebook when buying 2000 of them is 76c.
Then the total of money needed to order 1000 pens and 2000 notebooks is:
Total Money = 1000 × 0.60 + 2000 × 0.76 = $2120
Then, it costs $2120 to order 1000 pens and 2000 notebooks.
Answer:
b.1000
Step-by-step explanation:
6.74x-1.026=0.138
The smallest decimal goes to the thousandths place, so we need to multiply by 1000
.138
. tenths hundredths thousandths
Another way to look at it
.138 = 138/1000 so multiply by 1000 to get rid of the decimal
1.026 is to the same place value so we could pick either one to determine what to multiply by
It would be 0.38 the 8 is repeating
