Emily and her children went into a grocery store and she bought $20.80 worth of bananas and peaches. Each banana costs $0.80 and
-BARSIC- [3]

b + p = 14 and 0.80 b + 2 p = 20.80 are the system of equations.

Step-by-step explanation:

Step 1 :

Let b be the number of bananas

Let p be the number of peaches  

Given that the total of bananas and peaches that Emily bought  = 14

Hence we have,

b + p = 14

Step 2 :

Cost of one banana =  $0.80

Cost of one peach = $2

Cost of all the bananas and peaches Emily bought = $20.80

So sum of b bananas costing $0.80 and sum of p peaches costing $2 each is $20.80

Hence we have

0.80 b +2 p = 20.80

Solving for the above 2 equations we can get the value for b and p which will give the number of bananas and peaches bought

Step 3 :

Answer :

The system of equations that could be used to find the number of the bananas and the number of the peaches that Emily bought is given by

b + p = 14

0.80 b +2 p = 20.80

If you add​ Natalie's age and​ Fred's age, the result is 41. If you add​ Fred's age to 4 times​ Natalie's age, the result is 86.
max2010maxim [7]

Answer:

Fred = 26, Natalie = 15

Step-by-step explanation:

N + F= 41 // N = 41 - F (eqn 1)

4N + F = 86 (eqn 2)

sub eqn 1 into eqn 2

4(41 - F) + F = 86

164 - 4F + F = 86

-3F = - 78

F = 26

sub F = 26 into eqn 1

N = 41 - F

N = 41 - 26

N = 15
