Answer:
Total amount that Isaiah spent at the store is $27.44 .
Step-by-step explanation:
As given
Isaiah spent $19.60 on a gift for his mother.
The amount that he spent on the gift was [tex]\frac{5}{7}[/tex] of the total amount that he spent at the store.
As x represented the the total amount that Isaiah spent at the store .
Equation becomes
[tex]\frac{5}{7}\times x = 19.60[/tex]
[tex]\frac{5x}{7} = 19.60[/tex]
[tex]\frac{7\times 19.60}{5} = x[/tex]
[tex]\frac{7\times 19.60}{5} = x[/tex]
[tex]\frac{137.2}{5} = x[/tex]
x = $27.44
Therefore the total amount that Isaiah spent at the store is $27.44 .
