Question

Pears cost 0.92 per pound and apples cost 1.10 per pound.Mr Bonilla bought 3.75 punds of pears and 2.1 pounds of apples.how much did he pay for the pears and apples?

Answer 1

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

Find the total cost

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

the answer is

$5.76
