X = books were sold on Saturday.
Because 2 more books were sold on Sunday than on Saturday, therefore
(x + 2) books were sold on Sunday.
The total number of books sold over the weekend (Saturday and Sunday) is
x + (x+2)
= x + x + 2
= 2x + 2
Answer: 2x + 2
0.0181 yd/s. To solve this problem you use dimensional analysis. You convert the feet and minutes to yards and seconds by using this process. The units of feet and minutes cancel out, so you are left with yards per second. You should get 0.0180555555 when you multiply and divide everything, but you can just round it to 0.0181 or whatever place your teacher wants.
Answer:
$160
Step-by-step explanation:
In the monthly payment option she would pay $80 per month, therefore in a year (12 months) she would pay:
$80*12 = $960
We can see that this amount is greater than the $800 she would pay in the lump sum payment option.
The money she would save is:
$960 - $800 = $160
She would save<u> $160 yearly</u> with the lump sum payment option.
