7. Kroger decided to do a promotion on peanut butter. The starting price was $3.99 per jar. Each week, they would decrease the price by 6.2%. What is the price of
peanut butter after 6 weeks?
Write a equation and solve.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

so, converting firstly the mixed fractions to improper fractions and then "adding".
