Adam is buying some granola bars from the store. He finds a box of 6 Brain Grains granola bars for $4.74 and a box of 10 Nutty Crunch bars for $7.80. Which brand is the better value?

Nutty Crunch bars

Step-by-step explanation:

A box of 6 Brain Grains granola bars costs $4.74. The cost for one will be:

= $4.74 / 6

= $0.79

A box of 10 Nutty Crunch bars cost $7.80. The price per one will be:

= $7.80/10

= $0.78

The brand with the better value is Nutty Crunch bars

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
