Lauren went on a shopping spree and bought a purse, pair of jeans, and a scarf. the purse cost twice as much as the scarf, and the jeans were $25 more than the scarf. if she paid a total of $75 (not counting tax) what did each item cost ? urgent i’m having a hard time with this problem.

The scarf cost $12.50.

The purse cost $25.

The jeans cost $37.50.

If it was a total of 75 most likely everything was 25$ Each

The quotient is
7.5  × 10¹⁴


the  × still means multiplication. thus  × and  · mean the same operation

we have the following quotient

   

we can rewrite so that it becomes

   

3/4 = 0.75, which can be written as 7.5 × 10⁻¹ in scientific notation.
10²⁰ / 10⁵ is 10²⁰⁻⁵ = 10¹⁵ by exponent laws. then we have

   

if we multiply numbers with the same base, we add the exponents. thus the final answer is
