Answer:
The linear model of her monthly earnings is; Y =1200 +0.03*X. The amount earned is 1350; choice A
Step-by-step explanation:
Let Y denote her monthly earnings and X her total sales. The linear model can thus be formulated as; Y =1200 +0.03*X. We are then to find the value of Y given X =5000. We simply substitute X =5000 into the linear model which yields; Y =1350
Answer:
3710
Step-by-step explanation:
265 * 14
multiply 4 by 5, then 4 by 6, then 4 by 2 which would look like this 860
then you multiply 1 by 5, then 1 by 6, then 1 by 2 which should loo like 2650
it looks like that because for every digit you multiply by except the first you add a zero in front of it. then you add those two up which adds up to 3710 you're welcome. :}
Answer:
Price of (1) One way ticket = 487.75 QR
Price of (2) One way tickets = 487.75*2= 975.5 QR
Price for Return trip = 909 QR
Difference = 975.5-909 = 66.5 QR
There for Its is cheaper to buy to buy a return trip ticket by 66.5 QR
Ans: 60.50 QR
Andy's age = x
Jeff's age = x-2
Andy's age in five years = x+5
Jeff's age in five years = x-2+5
The sum of their ages in five years = x+5 + x-2+5
x + 5 + x - 2 + 5 = 40
2x + 8 = 40
<u> -8 -8</u>
2x = 32
<u> :2 :2</u>
x = 16
x - 2 = 14
<u>Andy is 16 years old and Jeff is 14 years old</u>
