Rani delivers bills to letterboxes and is paid $28 per thousand

a) how much does she earn for delivering 2500 items?
b) How many must she deliver to earn $100?
c) if she takes 6 hours to deliver each thousand on average, what is her hourly rate of pay?

a) $70

b) 4000 items

c)$4.67/hr

Step-by-step explanation:

a) simplest, 28 (per 1000) x2 plus 14 for 500

b) 28*4=112. it could be 3.57143, but no one wants part of an item

c) 28/6=4.66667

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
