Let

x---------> the number of pounds of pears

y---------> the number of pounds of apples

z---------> the total cost

we know that

z=0.92*x+1.10*y------> equation 1

x=3.75 lb-------> equation 2

y=2.1 lb -------> equation 3

<u>Find the total cost</u>

Substitute equation 2 and equation 3 in equation 1

z=0.92*(3.75)+1.10*(2.1)--------> z=3.45+2.31------------> z=$5.76

therefore

<u>the answer is</u>

$5.76

Help with number 12 and 13 And please show work so I can understand how to do it
Len [333]
13: multiply the amount by the tax rate (to make a percent a decimal move the decimal point 2 places to the left) and add the original amount and the taxed amount together. For 12 do above but then multiply the total by the tip rate and add together (basically the same as the tax again) :) I hope this helps
