Charlie's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Charlie $4.35 per pound, and type B coffee costs $5.80 per pound. This month, Charlie made 143 pounds of the blend, for a total cost of $713.40. How many pounds of type A coffee did he use

A=80 pounds, B=63 pounds

Step-by-step explanation:

Cost of type A=$4.35 per pound

Cost of type B=$5.80 per pound

Cost of A+ B=$713.40

A+B=143 pounds

A=143-B

QaPa+QbPb=713.40

A*4.35 + B*5.80=713.40

4.35A+5.80B=713.40

Substitute A=143-B

4.35(143-B) + 5.80B=713.40

622.05 - 4.35B + 5.80B=713.40

1.45B=713.40-622.05

1.45B=91.35

B=91.35/1.45

=63

B=63

Recall,

A+B=143

A+63=143

A=143-63

=80

A=80 pounds, B=63 pounds

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
