Step-by-step explanation:
The number of cones and sundaes sold at the ice cream parlor is 88 and 84 respectively.
<h3>Equation</h3>
There are three basic types of equation in mathematics. Namely:
- Linear equations
- Quadratic equations
- Simultaneous equations
- Cost of cones = $1.10
- Cost of sundaes = $2.35
- Total sold = 172
- Total cost = $294.20
- Number of cones = c
- Number of sundaes = s
c + s = 172
1.10c + 2.35s = 294.20
from (1)
c = 172 - s
substitute
1.10c + 2.35s = 294.20
1.10(172 - s) + 2.35s = 294.20
189.2 - 1.10s + 2.35s = 294.20
- 1.10s + 2.35s = 294.20 - 189.2
1.25s = 105
s = 105 ÷ 1.25
s = 84
Recall,
c + s = 172
c + 84 = 172
c = 172 - 84
c = 88
