Answer:
If he sells $2500 worth of merchandise, his salary is $800.
Step-by-step explanation:
You can find a function that gives you his salary as a function of the sales.
You have two points: (100, 500) and (700, 575).
y = mx + b
m = (575 - 500)/(700 - 100) = 75/600 = 0.125
Now use point (100, 500) to find b.
y = mx + b
500 = 0.125(100) + b
500 = 12.5 + b
b = 487.5
y = 0.125x + 487.5
If he sells $2500, then x = 2500.
y = 0.125x + 487.5
y = 0.125(2500) + 487.5
y = 800
If he sells $2500 worth of merchandise, his salary is $800.
You probably need to simply it is 2/3
Remark
<em><u>Two remarks</u></em>.
1. The weight of the ostrich is on the numerator of the ratio.
2. You have to change units of one of them to make the units the same.
Step One
Change the 150 kg to grams
150 kg * 1000 gram/1 kg = 150,000 grams
Step Two
Find the % of ostrich to hummingbird
Percent = (150,000 / 2) * 100%
Percent = 75000 * 100% = 7 500 000% larger.

Answer:
it would take 20 months and it would cost $6450
Step-by-step explanation:
in order to solve this question we need to equate the amount at each dealer against one another
<h2><u>Find the number of months</u></h2>
make the months as an unknown variable (x)
2450 + 200x = 2950 + 175x
now make x the subject of formula
200x - 175x = 2950 - 2450
25x = 500
x = 500/25
x = 20
the amount would be the same in <u>20 months </u>
<h2><u /></h2><h2><u>to find the amount it would be after those months</u></h2>
replace x with 20
2450 + 200 (20) = 6450
<u>$6450 </u>
