Eliza went to the store and bought 3 lbs of apples at $1.99 per lb, two loaves of bread at $.89 per loaf, a box of cereal at $3.99 per box, and a gallon of milk at $3.19 per gallon. if eliza paid with $20, how much change did she receive?

The amount of change she will receive is:

                           $ 5.07

This means that cost of 3 lbs of apple= $ (1.99×3)

i.e. cost of 3 lbs of apple= $ 5.97

Cost of 2 loaves= $ (0.89×2)

i.e.

Cost of 2 loaves= $ 1.78

This means that the total cost of his purchase is:

$ (5.97+1.78+3.99+3.19)

= $ 14.93

If Eliza paid with $20.

This means that the change she will receive is:

= $ (20-14.93)

= $ 5.07

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
